            DISTRICT OF COLUMBIA CIRCUIT.
                       No. 75-436.

[ Footnote * ] Together with No. 75-437, Buckley et al. v. Valeo,
Secretary of the United States Senate, et al., on appeal from the United
States District Court for the District of Columbia.

The Federal Election Campaign Act of 1971 (Act), as amended in
1974, (a) limits political contributions to candidates for federal elective
office by an individual or a group to $1,000 and by a political committee
to $5,000 to any single candidate per election, with an overall annual
limitation of $25,000 by an individual contributor; (b) limits expenditures
by individuals or groups "relative to a clearly identified candidate" to
$1,000 per candidate per election, and by a candidate from his personal
or family funds to various specified annual amounts depending upon the
federal office sought, and restricts overall general election and primary
campaign expenditures by candidates to various specified amounts,
again depending upon the federal office sought; (c) requires political
committees to keep detailed records of contributions and expenditures,
including the name and address of each individual contributing in excess
of $10, and his occupation and [424 U.S. 1, 2]  principal place of business
if his contribution exceeds $100, and to file quarterly reports with the
Federal Election Commission disclosing the source of every contribution
exceeding $100 and the recipient and purpose of every expenditure over
$100, and also requires every individual or group, other than a candidate
or political committee, making contributions or expenditures exceeding
$100 "other than by contribution to a political committee or candidate"
to file a statement with the Commission; and (d) creates the
eight-member Commission as the administering agency with
recordkeeping, disclosure, and investigatory functions and extensive
rulemaking, adjudicatory, and enforcement powers, and consisting of
two members appointed by the President pro tempore of the Senate,
two by the Speaker of the House, and two by the President (all subject
to confirmation by both Houses of Congress), and the Secretary of the
Senate and the Clerk of the House as ex officio nonvoting members.
Subtitle H of the Internal Revenue Code of 1954 (IRC), as amended in
1974, provides for public financing of Presidential nominating
conventions and general election and primary campaigns from general
revenues and allocates such funding to conventions and general election
campaigns by establishing three categories: (1) "major" parties (those
whose candidate received 25% or more of the vote in the most recent
election), which receive full funding, (2) "minor" parties (those whose
candidate received at least 5% but less than 25% of the votes at the last
election), which receive only a percentage of the funds to which the
major parties are entitled; and (3) "new" parties (all other parties), which
are limited to receipt of post-election funds or are not entitled to any
funds if their candidate receives less than 5% of the vote. A primary
candidate for the Presidential nomination by a political party who
receives more than $5,000 from private sources (counting only the first
$250 of each contribution) in each of at least 20 States is eligible for
matching public funds. Appellants (various federal officeholders and
candidates, supporting political organizations, and others) brought suit
against appellees (the Secretary of the Senate, Clerk of the House,
Comptroller General, Attorney General, and the Commission) seeking
declaratory and injective relief against the above statutory provisions on
various constitutional grounds. The Court of Appeals, on certified
questions from the District Court, upheld all but one of the statutory
provisions. A three-judge District Court upheld the constitutionality of
Subtitle H. Held: [424 U.S. 1, 3] 

     1. This litigation presents an Art. III "case or controversy," since
     the complaint discloses that at least some of the appellants have a
     sufficient "personal stake" in a determination of the constitutional
     validity of each of the challenged provisions to present "a real and
     substantial controversy admitting of specific relief through a
     decree of a conclusive character, as distinguished from an opinion
     advising what the law would be upon a hypothetical state of
     facts." Aetna Life Ins. Co. v. Haworth, 300 U.S. 227, 241 . Pp.
     11-12. 
     2. The Act's contribution provisions are constitutional, but the
     expenditure provisions violate the First Amendment. Pp. 12-59. 
          (a) The contribution provisions, along with those covering
          disclosure, are appropriate legislative weapons against the
          reality or appearance of improper influence stemming from
          the dependence of candidates on large campaign
          contributions, and the ceilings imposed accordingly serve
          the basic governmental interest in safeguarding the integrity
          of the electoral process without directly impinging upon the
          rights of individual citizens and candidates to engage in
          political debate and discussion. Pp. 23-38. 
          (b) The First Amendment requires the invalidation of the
          Act's independent expenditure ceiling, its limitation on a
          candidate's expenditures from his own personal funds, and
          its ceilings on overall campaign expenditures, since those
          provisions place substantial and direct restrictions on the
          ability of candidates, citizens, and associations to engage in
          protected political expression, restrictions that the First
          Amendment cannot tolerate. Pp. 39-59. 
     3. The Act's disclosure and recordkeeping provisions are
     constitutional. Pp. 60-84. 
          (a) The general disclosure provisions, which serve
          substantial governmental interests in informing the
          electorate and preventing the corruption of the political
          process, are not overbroad insofar as they apply to
          contributions to minor parties and independent candidates.
          No blanket exemption for minor parties is warranted since
          such parties in order to prove injury as a result of
          application to them of the disclosure provisions need show
          only a reasonable probability that the compelled disclosure
          of a party's contributors' names will subject them to threats,
          harassment, or reprisals in violation of their First
          Amendment associational rights. Pp. 64-74. 
          (b) The provision for disclosure by those who make
          independent [424 U.S. 1, 4]  contributions and expenditures,
          as narrowly construed to apply only (1) when they make
          contributions earmarked for political purposes or
          authorized or requested by a candidate or his agent to
          some person other than a candidate or political committee
          and (2) when they make an expenditure for a
          communication that expressly advocates the election or
          defeat of a clearly identified candidate is not
          unconstitutionally vague and does not constitute a prior
          restraint but is a reasonable and minimally restrictive
          method of furthering First Amendment values by public
          exposure of the federal election system. Pp. 74-82. 
          (c) The extension of the recordkeeping provisions to
          contributions as small as those just above $10 and the
          disclosure provisions to contributions above $100 is not on
          this record overbroad since it cannot be said to be
          unrelated to the informational and enforcement goals of the
          legislation. Pp. 82-84. 
     4. Subtitle H of the IRC is constitutional. Pp. 85-109. 
          (a) Subtitle H is not invalid under the General Welfare
          Clause but, as a means to reform the electoral process,
          was clearly a choice within the power granted to Congress
          by the Clause to decide which expenditures will promote
          the general welfare. Pp. 90-92. 
          (b) Nor does Subtitle H violate the First Amendment.
          Rather than abridging, restricting, or censoring speech, it
          represents an effort to use public money to facilitate and
          enlarge public discussion and participation in the electoral
          process. Pp. 92-93. 
          (c) Subtitle H, being less burdensome than ballot-access
          regulations and having been enacted in furtherance of vital
          governmental interests in relieving major-party candidates
          from the rigors of soliciting private contributions, in not
          funding candidates who lack significant public support, and
          in eliminating reliance on large private contributions for
          funding of conventions and campaigns, does not invidiously
          discriminate against minor and new parties in violation of
          the Due Process Clause of the Fifth Amendment. Pp.
          93-108. 
          (d) Invalidation of the spending-limit provisions of the Act
          does not render Subtitle H unconstitutional, but the Subtitle
          is severable from such provisions and is not dependent
          upon the existence of a generally applicable expenditure
          limit. Pp. 108-109. 
     5. The Commission's composition as to all but its investigative and
     informative powers violates Art. II, 2, cl. 2. With respect to the
     Commission's powers, all of which are ripe for review, [424 U.S. 1,
     5]  to enforce the Act, including primary responsibility for bringing
     civil actions against violators, to make rules for carrying out the
     Act, to temporarily disqualify federal candidates for failing to file
     required reports, and to authorize convention expenditures in
     excess of the specified limits, the provisions of the Act vesting
     such powers in the Commission and the prescribed method of
     appointment of members of the Commission to the extent that a
     majority of the voting members are appointed by the President
     pro tempore of the Senate and the Speaker of the House, violate
     the Appointments Clause, which provides in pertinent part that the
     President shall nominate, and with the Senate's advice and
     consent appoint, all "Officers of the United States," whose
     appointments are not otherwise provided for, but that Congress
     may vest the appointment of such inferior officers, as it deems
     proper, in the President alone, in the courts, or in the heads of
     departments. Hence (though the Commission's past acts are
     accorded de facto validity and a stay is granted permitting it to
     function under the Act for not more than 30 days), the
     Commission, as presently constituted, may not because of that
     Clause exercise such powers, which can be exercised only by
     "Officers of the United States" appointed in conformity with the
     Appointments Clause, although it may exercise such investigative
     and informative powers as are in the same category as those
     powers that Congress might delegate to one of its own
     committees. Pp. 109-143. 

No. 75-436, 171 U.S. App. D.C. 172, 519 F.2d 821, affirmed in part
and reversed in part; No. 75-437, 401 F. Supp. 1235, affirmed.

PER CURIAM.

These appeals present constitutional challenges to the key provisions of
the Federal Election Campaign Act of 1971 (Act), and related
provisions of the Internal Revenue Code of 1954, all as amended in
1974.[1]  [424 U.S. 1, 7]  

The Court of Appeals, in sustaining the legislation in large part against
various constitutional challenges,[2] viewed it as "by far the most
comprehensive reform legislation [ever] passed by Congress concerning
the election of the President, Vice-President, and members of
Congress." 171 U.S. App. D.C. 172, 182, 519 F.2d 821, 831 (1975).
The statutes at issue summarized in broad terms, contain the following
provisions: (a) individual political contributions are limited to $1,000 to
any single candidate per election, with an overall annual limitation of
$25,000 by any contributor; independent expenditures by individuals
and groups "relative to a clearly identified candidate" are limited to
$1,000 a year; campaign spending by candidates for various federal
offices and spending for national conventions by political parties are
subject to prescribed limits; (b) contributions and expenditures above
certain threshold levels must be reported and publicly disclosed; (c) a
system for public funding of Presidential campaign activities is
established by Subtitle H of the Internal Revenue Code;[3] and (d) a
Federal Election Commission is established to administer and enforce
the legislation.

This suit was originally filed by appellants in the United States District
Court for the District of Columbia. Plaintiffs included a candidate for the
Presidency of the United States, a United States Senator who is a
candidate for re-election, a potential contributor, the [424 U.S. 1, 8] 
Committee for a Constitutional Presidency - McCarthy '76, the
Conservative Party of the State of New York, the Mississippi
Republican Party, the Libertarian Party, the New York Civil Liberties
Union, Inc., the American Conservative Union, the Conservative Victory
Fund, and Human Events, Inc. The defendants included the Secretary of
the United States Senate and the Clerk of the United States House of
Representatives, both in their official capacities and as ex officio
members of the Federal Election Commission. The Commission itself
was named as a defendant. Also named were the Attorney General of
the United States and the Comptroller General of the United States.

Jurisdiction was asserted under 28 U.S.C. 1331, 2201, and 2202, and
315 (a) of the Act, 2 U.S.C. 437h (a) (1970 ed., Supp. IV).[4] The
complaint sought both a [424 U.S. 1, 9]   declaratory judgment that the
major provisions of the Act were unconstitutional and an injunction
against enforcement of those provisions. Appellants requested the
convocation of a three-judge District Court as to all matters and also
requested certification of constitutional questions to the Court of
Appeals, pursuant to the terms of 315 (a). The District Judge denied the
application for a three-judge court and directed that the case be
transmitted to the Court of Appeals. That court entered an order stating
that the case was "preliminarily deemed" to be properly certified under
315 (a). Leave to intervene was granted to various groups and
individuals.[5] After considering matters regarding factfinding
procedures, the Court of Appeals entered an order en banc remanding
the case to the District Court to (1) identify the constitutional issues in
the complaint; (2) take whatever evidence was found necessary in
addition to the submissions suitably dealt with by way of judicial notice;
(3) make findings of fact with reference to those issues; and (4) certify
the constitutional questions arising from the foregoing steps to the Court
of Appeals.[6] On remand, the District [424 U.S. 1, 10]  Judge entered a
memorandum order adopting extensive findings of fact and transmitting
the augmented record back to the Court of Appeals.

On plenary review, a majority of the Court of Appeals rejected, for the
most part, appellants' constitutional attacks. The court found "a clear and
compelling interest," 171 U.S. App. D.C., at 192, 519 F.2d, at 841, in
preserving the integrity of the electoral process. On that basis, the court
upheld, with one exception,[7] the substantive provisions of the Act with
respect to contributions, expenditures, and disclosure. It also sustained
the constitutionality of the newly established Federal Election
Commission. The court concluded that, notwithstanding the manner of
selection of its members and the breadth of its powers, which included
nonlegislative functions, the Commission is a constitutionally authorized
agency created to perform primarily legislative functions.[8]  [424 U.S. 1,
11]  The provisions for public funding of the three stages of the
Presidential selection process were upheld as a valid exercise of
congressional power under the General Welfare Clause of the
Constitution, Art. I, 8.

In this Court, appellants argue that the Court of Appeals failed to give
this legislation the critical scrutiny demanded under accepted First
Amendment and equal protection principles. In appellants' view, limiting
the use of money for political purposes constitutes a restriction on
communication violative of the First Amendment, since virtually all
meaningful political communications in the modern setting involve the
expenditure of money. Further, they argue that the reporting and
disclosure provisions of the Act unconstitutionally impinge on their right
to freedom of association. Appellants also view the federal subsidy
provisions of Subtitle H as violative of the General Welfare Clause, and
as inconsistent with the First and Fifth Amendments. Finally, appellants
renew their attack on the Commission's composition and powers.

At the outset we must determine whether the case before us presents a
"case or controversy" within the meaning of Art. III of the Constitution.
Congress may not, of course, require this Court to render opinions in
matters which are not "cases or controversies." Aetna Life Ins. Co. v.
Haworth, 300 U.S. 227, 240 -241 (1937). We must therefore decide
whether appellants have the "personal stake in the outcome of the
controversy" necessary to meet the requirements of Art. III. Baker v.
Carr, 369 U.S. 186, 204 (1962). It is clear that Congress, in enacting
[424 U.S. 1, 12]  2 U.S.C. 437h (1970 ed., Supp. IV),[9] intended to
provide judicial review to the extent permitted by Art. III. In our view,
the complaint in this case demonstrates that at least some of the
appellants have a sufficient "personal stake"[10] in a determination of the
constitutional validity of each of the challenged provisions to present "a
real and substantial controversy admitting of specific relief through a
decree of a conclusive character, as distinguished from an opinion
advising what the law would be upon a hypothetical state of facts."
Aetna Life Ins. Co. v. Haworth, supra, at 241.[11] 

     I. CONTRIBUTION AND EXPENDITURE LIMITATIONS 

The intricate statutory scheme adopted by Congress to regulate federal
election campaigns includes restrictions [424 U.S. 1, 13]  on political
contributions and expenditures that apply broadly to all phases of and all
participants in the election process. The major contribution and
expenditure limitations in the Act prohibit individuals from contributing
more than $25,000 in a single year or more than $1,000 to any single
candidate for an election campaign[12] and from spending more than
$1,000 a year "relative to a clearly identified candidate." [13] Other
provisions restrict a candidate's use of personal and family resources in
his campaign[14] and limit the overall amount that can be spent by a
candidate in campaigning for federal office.[15] 

The constitutional power of Congress to regulate federal elections is well
established and is not questioned by any of the parties in this case. [16]
Thus, the critical constitutional [424 U.S. 1, 14]  questions presented here
go not to the basic power of Congress to legislate in this area, but to
whether the specific legislation that Congress has enacted interferes with
First Amendment freedoms or invidiously discriminates against
nonincumbent candidates and minor parties in contravention of the Fifth
Amendment.

     A. General Principles 

The Act's contribution and expenditure limitations operate in an area of
the most fundamental First Amendment activities. Discussion of public
issues and debate on the qualifications of candidates are integral to the
operation of the system of government established by our Constitution.
The First Amendment affords the broadest protection to such political
expression in order "to assure [the] unfettered interchange of ideas for
the bringing about of political and social changes desired by the people."
Roth v. United States, 354 U.S. 476, 484 (1957). Although First
Amendment protections are not confined to "the exposition of ideas,"
Winters v. New York, 333 U.S. 507, 510 (1948), "there is practically
universal agreement that a major purpose of that Amendment was to
protect the free discussion of governmental affairs, ... of course
includ[ing] discussions of candidates . . . ." Mills v. Alabama, 384 U.S.
214, 218 (1966). This no more than reflects our "profound national
commitment to the principle that debate on public issues should be
uninhibited, robust, and wide-open," New York Times Co. v. Sullivan,
376 U.S. 254, 270 (1964). In a republic where the people are
sovereign, the ability of the citizenry to make informed choices among
candidates [424 U.S. 1, 15]  for office is essential, for the identities of those
who are elected will inevitably shape the course that we follow as a
nation. As the Court observed in Monitor Patriot Co. v. Roy, 401 U.S.
265, 272 (1971), "it can hardly be doubted that the constitutional
guarantee has its fullest and most urgent application precisely to the
conduct of campaigns for political office."

The First Amendment protects political association as well as political
expression. The constitutional right of association explicated in NAACP
v. Alabama, 357 U.S. 449, 460 (1958), stemmed from the Court's
recognition that "[e]ffective advocacy of both public and private points
of view, particularly controversial ones, is undeniably enhanced by group
association." Subsequent decisions have made clear that the First and
Fourteenth Amendments guarantee "`freedom to associate with others
for the common advancement of political beliefs and ideas,'" a freedom
that encompasses "`[t]he right to associate with the political party of
one's choice.'" Kusper v. Pontikes, 414 U.S. 51, 56 , 57 (1973),
quoted in Cousins v. Wigoda, 419 U.S. 477, 487 (1975).

It is with these principles in mind that we consider the primary
contentions of the parties with respect to the Act's limitations upon the
giving and spending of money in political campaigns. Those conflicting
contentions could not more sharply define the basic issues before us.
Appellees contend that what the Act regulates is conduct, and that its
effect on speech and association is incidental at most. Appellants
respond that contributions and expenditures are at the very core of
political speech, and that the Act's limitations thus constitute restraints on
First Amendment liberty that are both gross and direct.

In upholding the constitutional validity of the Act's contribution and
expenditure provisions on the ground [424 U.S. 1, 16]  that those provisions
should be viewed as regulating conduct, not speech, the Court of
Appeals relied upon United States v. O'Brien, 391 U.S. 367 (1968).
See 171 U.S. App. D.C., at 191, 519 F.2d, at 840. The O'Brien case
involved a defendant's claim that the First Amendment prohibited his
prosecution for burning his draft card because his act was "`symbolic
speech'" engaged in as a "`demonstration against the war and against the
draft.'" 391 U.S., at 376 . On the assumption that "the alleged
communicative element in O'Brien's conduct [was] sufficient to bring into
play the First Amendment," the Court sustained the conviction because it
found "a sufficiently important governmental interest in regulating the
non-speech element" that was "unrelated to the suppression of free
expression" and that had an "incidental restriction on alleged First
Amendment freedoms ... no greater than [was] essential to the
furtherance of that interest." Id., at 376-377. The Court expressly
emphasized that O'Brien was not a case "where the alleged
governmental interest in regulating conduct arises in some measure
because the communication allegedly integral to the conduct is itself
thought to be harmful." Id., at 382. 

We cannot share the view that the present Act's contribution and
expenditure limitations are comparable to the restrictions on conduct
upheld in O'Brien. The expenditure of money simply cannot be equated
with such conduct as destruction of a draft card. Some forms of
communication made possible by the giving and spending of money
involve speech alone, some involve conduct primarily, and some involve
a combination of the two. Yet this Court has never suggested that the
dependence of a communication on the expenditure of money operates
itself to introduce a non speech element or to reduce the exacting
scrutiny required by the First Amendment. See Bigelow v. Virginia, 421
U.S. 809 , [424 U.S. 1, 17]  820 (1975); New York Times Co. v. Sullivan,
supra, at 266. For example, in Cox v. Louisiana, 379 U.S. 559 (1965),
the Court contrasted picketing and parading with a newspaper comment
and a telegram by a citizen to a public official. The parading and
picketing activities were said to constitute conduct "intertwined with
expression and association," whereas the newspaper comment and the
telegram were described as a "pure form of expression" involving "free
speech alone" rather than "expression mixed with particular conduct."
Id., at 563-564.

Even if the categorization of the expenditure of money as conduct were
accepted, the limitations challenged here would not meet the O'Brien test
because the governmental interests advanced in support of the Act
involve "suppressing communication." The interests served by the Act
include restricting the voices of people and interest groups who have
money to spend and reducing the overall scope of federal election
campaigns. Although the Act does not focus on the ideas expressed by
persons or groups subject to its regulations, it is aimed in part at
equalizing the relative ability of all voters to affect electoral outcomes by
placing a ceiling on expenditures for political expression by citizens and
groups. Unlike O'Brien, where the Selective Service System's
administrative interest in the preservation of draft cards was wholly
unrelated to their use as a means of communication, it is beyond dispute
that the interest in regulating the alleged "conduct" of giving or spending
money "arises in some measure because the communication allegedly
integral to the conduct is itself thought to be harmful." 391 U.S., at 382 .

Nor can the Act's contribution and expenditure limitations be sustained,
as some of the parties suggest, by reference to the constitutional
principles reflected in such [424 U.S. 1, 18]  decisions as Cox v. Louisiana,
supra; Adderley v. Florida, 385 U.S. 39 (1966); and Kovacs v.
Cooper, 336 U.S. 77 (1949). Those cases stand for the proposition that
the government may adopt reasonable time, place, and manner
regulations, which do not discriminate among speakers or ideas, in order
to further an important governmental interest unrelated to the restriction
of communication. See Erznoznik v. City of Jacksonville, 422 U.S. 205,
209 (1975). In contrast to O'Brien, where the method of expression
was held to be subject to prohibition, Cox, Adderley, and Kovacs
involved place or manner restrictions on legitimate modes of expression
- picketing, parading, demonstrating, and using a soundtruck. The critical
difference between this case and those time, place, and manner cases is
that the present Act's contribution and expenditure limitations impose
direct quantity restrictions on political communication and association by
persons, groups, candidates, and political parties in addition to any
reasonable time, place, and manner regulations otherwise imposed.[17] 
[424 U.S. 1, 19]  

A restriction on the amount of money a person or group can spend on
political communication during a campaign necessarily reduces the
quantity of expression by restricting the number of issues discussed, the
depth of their exploration, and the size of the audience reached.[18] This
is because virtually every means of communicating ideas in today's mass
society requires the expenditure of money. The distribution of the
humblest handbill or leaflet entails printing, paper, and circulation costs.
Speeches and rallies generally necessitate hiring a hall and publicizing the
event. The electorate's increasing dependence on television, radio, and
other mass media for news and information has made these expensive
modes of communication indispensable instruments of effective political
speech.

The expenditure limitations contained in the Act represent substantial
rather than merely theoretical restraints on the quantity and diversity of
political speech. The $1,000 ceiling on spending "relative to a clearly
identified candidate," 18 U.S.C. 608 (e) (1) (1970 ed., Supp. IV),
would appear to exclude all citizens and groups except candidates,
political parties, and the institutional press[19] from any significant use of
the most [424 U.S. 1, 20]   effective modes of communication.[20] Although
the Act's limitations on expenditures by campaign organizations and
political parties provide substantially greater room for discussion and
debate, they would have required restrictions in the scope of a number
of past congressional and Presidential campaigns [21] and would operate
to constrain campaigning by candidates who raise sums in excess of the
spending ceiling.

By contrast with a limitation upon expenditures for political expression, a
limitation upon the amount that any one person or group may contribute
to a candidate or political committee entails only a marginal restriction
upon the contributor's ability to engage in free communication. [424 U.S. 1,
21]  A contribution serves as a general expression of support for the
candidate and his views, but does not communicate the underlying basis
for the support. The quantity of communication by the contributor does
not increase perceptibly with the size of his contribution, since the
expression rests solely on the undifferentiated, symbolic act of
contributing. At most, the size of the contribution provides a very rough
index of the intensity of the contributor's support for the candidate.[22] A
limitation on the amount of money a person may give to a candidate or
campaign organization thus involves little direct restraint on his political
communication, for it permits the symbolic expression of support
evidenced by a contribution but does not in any way infringe the
contributor's freedom to discuss candidates and issues. While
contributions may result in political expression if spent by a candidate or
an association to present views to the voters, the transformation of
contributions into political debate involves speech by someone other
than the contributor. 

Given the important role of contributions in financing political campaigns,
contribution restrictions could have a severe impact on political dialogue
if the limitations prevented candidates and political committees from
amassing the resources necessary for effective advocacy. There is no
indication, however, that the contribution limitations imposed by the Act
would have any dramatic adverse effect on the funding of campaigns and
political associations. [23] The overall effect of the Act's contribution [424
U.S. 1, 22]  ceilings is merely to require candidates and political
committees to raise funds from a greater number of persons and to
compel people who would otherwise contribute amounts greater than
the statutory limits to expend such funds on direct political expression,
rather than to reduce the total amount of money potentially available to
promote political expression. 

The Act's contribution and expenditure limitations also impinge on
protected associational freedoms. Making a contribution, like joining a
political party, serves to affiliate a person with a candidate. In addition, it
enables like-minded persons to pool their resources in furtherance of
common political goals. The Act's contribution ceilings thus limit one
important means of associating with a candidate or committee, but leave
the contributor free to become a member of any political association and
to assist personally in the association's efforts on behalf of candidates.
And the Act's contribution limitations permit associations and candidates
to aggregate large sums of money to promote effective advocacy. By
contrast, the Act's $1,000 limitation on independent expenditures
"relative to a clearly identified candidate" precludes most associations
from effectively amplifying the voice of their adherents, the original basis
for the recognition of First Amendment protection of the freedom of
association. See NAACP v. Alabama, 357 U.S., at 460 . The Act's
constraints on the ability of independent associations and candidate
campaign organizations to expend resources on political expression "is
simultaneously an interference with the freedom of [their] adherents,"
Sweezy v. New Hampshire, 354 U.S. 234, 250 (1957) (plurality
opinion). See Cousins v. [424 U.S. 1, 23]  Wigoda, 419 U.S., at 487 -488;
NAACP v. Button, 371 U.S. 415, 431 (1963).

In sum, although the Act's contribution and expenditure limitations both
implicate fundamental First Amendment interests, its expenditure ceilings
impose significantly more severe restrictions on protected freedoms of
political expression and association than do its limitations on financial
contributions.

     B. Contribution Limitations 

1. The $1,000 Limitation on Contributions by Individuals and Groups to
Candidates and Authorized Campaign Committees

Section 608 (b) provides, with certain limited exceptions, that "no
person shall make contributions to any candidate with respect to any
election for Federal office which, in the aggregate, exceed $1,000." The
statute defines "person" broadly to include "an individual, partnership,
committee, association, corporation or any other organization or group
of persons." 591 (g). The limitation reaches a gift, subscription, loan,
advance, deposit of anything of value, or promise to give a contribution,
made for the purpose of influencing a primary election, a Presidential
preference primary, or a general election for any federal office. [24] 591
(e) (1), (2). The [424 U.S. 1, 24]  $1,000 ceiling applies regardless of
whether the contribution is given to the candidate, to a committee
authorized in writing by the candidate to accept contributions on his
behalf, or indirectly via earmarked gifts passed through an intermediary
to the candidate. 608 (b) (4), (6).[25] The restriction applies to
aggregate amounts contributed to the candidate for each election -- with
primaries, runoff elections, and general elections counted separately, and
all Presidential primaries held in any calendar year treated together as a
single election campaign. 608 (b) (5).

Appellants contend that the $1,000 contribution ceiling unjustifiably
burdens First Amendment freedoms, employs overbroad dollar limits,
and discriminates against candidates opposing incumbent officeholders
and against minor-party candidates in violation of the Fifth Amendment.
We address each of these claims of invalidity in turn.

     (a) 

As the general discussion in Part I-A, supra, indicated, the primary First
Amendment problem raised by the Act's contribution limitations is their
restriction of one aspect of the contributor's freedom of political
association. [424 U.S. 1, 25]  The Court's decisions involving associational
freedoms establish that the right of association is a "basic constitutional
freedom," Kusper v. Pontikes, 414 U.S., at 57 , that is "closely allied to
freedom of speech and a right which, like free speech, lies at the
foundation of a free society." Shelton v. Tucker, 364 U.S. 479, 486
(1960). See, e. g., Bates v. Little Rock, 361 U.S. 516, 522 -523
(1960); NAACP v. Alabama, supra, at 460-461; NAACP v. Button,
supra, at 452 (Harlan, J., dissenting). In view of the fundamental nature
of the right to associate, governmental "action which may have the effect
of curtailing the freedom to associate is subject to the closest scrutiny."
NAACP v. Alabama, supra, at 460-461. Yet, it is clear that "[n]either
the right to associate nor the right to participate in political activities is
absolute." CSC v. Letter Carriers, 413 U.S. 548, 567 (1973). Even a
"`significant interference' with protected rights of political association"
may be sustained if the State demonstrates a sufficiently important
interest and employs means closely drawn to avoid unnecessary
abridgment of associational freedoms. Cousins v. Wigoda, supra, at
488; NAACP v. Button, supra, at 438; Shelton v. Tucker, supra, at
488.

Appellees argue that the Act's restrictions on large campaign
contributions are justified by three governmental interests. According to
the parties and amici, the primary interest served by the limitations and,
indeed, by the Act as a whole, is the prevention of corruption and the
appearance of corruption spawned by the real or imagined coercive
influence of large financial contributions on candidates' positions and on
their actions if elected to office. Two "ancillary" interests underlying the
Act are also allegedly furthered by the $1,000 limits on contributions.
First, the limits serve to mute the voices of affluent persons and groups in
the election [424 U.S. 1, 26]  process and thereby to equalize the relative
ability of all citizens to affect the outcome of elections.[26] Second, it is
argued, the ceilings may to some extent act as a brake on the
skyrocketing cost of political campaigns and thereby serve to open the
political system more widely to candidates without access to sources of
large amounts of money. [27] 

It is unnecessary to look beyond the Act's primary purpose -- to limit
the actuality and appearance of corruption resulting from large individual
financial contributions -- in order to find a constitutionally sufficient
justification for the $1,000 contribution limitation. Under a system of
private financing of elections, a candidate lacking immense personal or
family wealth must depend on financial contributions from others to
provide the resources necessary to conduct a successful campaign. The
increasing importance of the communications media and sophisticated
mass-mailing and polling operations to effective campaigning make the
raising of large sums of money an ever more essential ingredient of an
effective candidacy. To the extent that large contributions are given to
secure a political quid pro quo from current and potential office holders,
the integrity of our system of [424 U.S. 1, 27]  representative democracy is
undermined. Although the scope of such pernicious practices can never
be reliably ascertained, the deeply disturbing examples surfacing after the
1972 election demonstrate that the problem is not an illusory one. [28] 

Of almost equal concern as the danger of actual quid pro quo
arrangements is the impact of the appearance of corruption stemming
from public awareness of the opportunities for abuse inherent in a regime
of large individual financial contributions. In CSC v. Letter Carriers,
supra, the Court found that the danger to "fair and effective government"
posed by partisan political conduct on the part of federal employees
charged with administering the law was a sufficiently important concern
to justify broad restrictions on the employees' right of partisan political
association. Here, as there, Congress could legitimately conclude that
the avoidance of the appearance of improper influence "is also critical ...
if confidence in the system of representative Government is not to be
eroded to a disastrous extent." 413 U.S., at 565 .[29]  

Appellants contend that the contribution limitations must be invalidated
because bribery laws and narrowly drawn disclosure requirements
constitute a less restrictive means of dealing with "proven and suspected
quid pro quo arrangements." But laws making criminal [424 U.S. 1, 28]  the
giving and taking of bribes deal with only the most blatant and specific
attempts of those with money to influence governmental action. And
while disclosure requirements serve the many salutary purposes
discussed elsewhere in this opinion,[30] Congress was surely entitled to
conclude that disclosure was only a partial measure, and that
contribution ceilings were a necessary legislative concomitant to deal
with the reality or appearance of corruption inherent in a system
permitting unlimited financial contributions, even when the identities of
the contributors and the amounts of their contributions are fully
disclosed. 

The Act's $1,000 contribution limitation focuses precisely on the
problem of large campaign contributions -- the narrow aspect of political
association where the actuality and potential for corruption have been
identified -- while leaving persons free to engage in independent political
expression, to associate actively through volunteering their services, and
to assist to a limited but nonetheless substantial extent in supporting
candidates and committees with financial resources.[31] Significantly, the
[424 U.S. 1, 29]  Act's contribution limitations in themselves do not
undermine to any material degree the potential for robust and effective
discussion of candidates and campaign issues by individual citizens,
associations, the institutional press, candidates, and political parties.

We find that, under the rigorous standard of review established by our
prior decisions, the weighty interests served by restricting the size of
financial contributions to political candidates are sufficient to justify the
limited effect upon First Amendment freedoms caused by the $1,000
contribution ceiling. 

     (b) 

Appellants' first overbreadth challenge to the contribution ceilings rests
on the proposition that most large contributors do not seek improper
influence over a candidate's position or an officeholder's action.
Although the truth of that proposition may be assumed, it does not [424
U.S. 1, 30]  undercut the validity of the $1,000 contribution limitation. Not
only is it difficult to isolate suspect contributions but, more importantly,
Congress was justified in concluding that the interest in safeguarding
against the appearance of impropriety requires that the opportunity for
abuse inherent in the process of raising large monetary contributions be
eliminated.

A second, related overbreadth claim is that the $1,000 restriction is
unrealistically low because much more than that amount would still not
be enough to enable an unscrupulous contributor to exercise improper
influence over a candidate or officeholder, especially in campaigns for
statewide or national office. While the contribution limitation provisions
might well have been structured to take account of the graduated
expenditure limitations for congressional and Presidential campaigns,[32]
Congress' failure to engage in such fine tuning does not invalidate the
legislation. As the Court of Appeals observed, "[i]f it is satisfied that
some limit on contributions is necessary, a court has no scalpel to probe,
whether, say, a $2,000 ceiling might not serve as well as $1,000." 171
U.S. App. D.C., at 193, 519 F.2d, at 842. Such distinctions in degree
become significant only when they can be said to amount to differences
in kind. Compare Kusper v. Pontikes, 414 U.S. 51 (1973), with
Rosario v. Rockefeller, 410 U.S. 752 (1973).

     (c) 

Apart from these First Amendment concerns, appellants argue that the
contribution limitations work such an invidious discrimination between
incumbents [424 U.S. 1, 31]  and challengers that the statutory provisions
must be declared unconstitutional on their face.[33] In considering this
contention, it is important at the outset to note that the Act applies the
same limitations on contributions to all candidates regardless of their
present occupations, ideological views, or party affiliations. Absent
record evidence of invidious discrimination against challengers as a class,
a court should generally be hesitant to invalidate legislation which on its
face imposes evenhanded restrictions. Cf. James v. Valtierra, 402 U.S.
137 (1971). [424 U.S. 1, 32]  

There is no such evidence to support the claim that the contribution
limitations in themselves discriminate against major-party challengers to
incumbents. Challengers can and often do defeat incumbents in federal
elections.[34] Major-party challengers in federal elections are usually
men and women who are well known and influential in their community
or State. Often such challengers are themselves incumbents in important
local, state, or federal offices. Statistics in the record indicate that
major-party challengers as well as incumbents are capable of raising
large sums for campaigning.[35] Indeed, a small but nonetheless
significant number of challengers have in recent elections outspent their
incumbent rivals.[36] And, to the extent that incumbents generally are
more likely than challengers to attract very large contributions, the Act's
$1,000 ceiling has the practical effect of benefiting challengers as a
class.[37] Contrary to the broad generalization [424 U.S. 1, 33]   drawn by
the appellants, the practical impact of the contribution ceilings in any
given election will clearly depend upon the amounts in excess of the
ceilings that, for various reasons, the candidates in that election would
otherwise have received and the utility of these additional amounts to the
candidates. To be sure, the limitations may have a significant effect on
particular challengers or incumbents, but the record provides no basis
for predicting that such adventitious factors will invariably and invidiously
benefit incumbents as a class.[38] Since the danger of corruption and the
appearance of corruption apply with equal force to challengers and to
incumbents, Congress had ample justification for imposing the same
fundraising constraints upon both.

The charge of discrimination against minor-party and independent
candidates is more troubling, but the record provides no basis for
concluding that the Act invidiously disadvantages such candidates. As
noted above, the Act on its face treats all candidates equally with regard
to contribution limitations. And the restriction would appear to benefit
minor-party and independent candidates relative to their major-party
opponents because major-party candidates receive far more money in
large contributions.[39] Although there is some [424 U.S. 1, 34]   force to
appellants' response that minor-party candidates are primarily concerned
with their ability to amass the resources necessary to reach the electorate
rather than with their funding position relative to their major-party
opponents, the record is virtually devoid of support for the claim that the
$1,000 contribution limitation will have a serious effect on the initiation
and scope of minor-party and independent candidacies. [40] Moreover,
any attempt [424 U.S. 1, 35]  to exclude minor parties and independents en
masse from the Act's contribution limitations overlooks the fact that
minor-party candidates may win elective office or have a substantial
impact on the outcome of an election.[41]  

In view of these considerations, we conclude that the impact of the Act's
$1,000 contribution limitation on major-party challengers and on
minor-party candidates does not render the provision unconstitutional on
its face.

2. The $5,000 Limitation on Contributions by Political Committees 

Section 608 (b) (2) permits certain committees, designated as "political
committees," to contribute up to $5,000 to any candidate with respect to
any election for federal office. In order to qualify for the higher
contribution ceiling, a group must have been registered with the
Commission as a political committee under 2 U.S.C. 433 (1970 ed.,
Supp. IV) for not less than six months, have received contributions from
more than 50 persons, and, except for state political party organizations,
have contributed to five or more candidates for federal office. Appellants
argue that these qualifications unconstitutionally discriminate against ad
hoc organizations in favor of established interest groups and
impermissibly burden free association. The argument is without merit.
Rather than undermining freedom of association, the basic provision
enhances the opportunity of bona fide groups to participate in the
election process, and the registration, contribution, and candidate
conditions serve the permissible purpose of preventing individuals [424
U.S. 1, 36]  from evading the applicable contribution limitations by labeling
themselves committees.

3. Limitations on Volunteers' Incidental Expenses

The Act excludes from the definition of contribution "the value of
services provided without compensation by individuals who volunteer a
portion or all of their time on behalf of a candidate or political
committee." 591 (e) (5) (A). Certain expenses incurred by persons in
providing volunteer services to a candidate are exempt from the $1,000
ceiling only to the extent that they do not exceed $500. These expenses
are expressly limited to (1) "the use of real or personal property and the
cost of invitations, food, and beverages, voluntarily provided by an
individual to a candidate in rendering voluntary personal services on the
individual's residential premises for candidate-related activities." 591 (e)
(5) (B); (2) "the sale of any food or beverage by a vendor for use in a
candidate's campaign at a charge [at least equal to cost but] less than the
normal comparable charge," 591 (e) (5) (C); and (3) "any unreimbursed
payment for travel expenses made by an individual who on his own
behalf volunteers his personal services to a candidate," 591 (e) (5) (D).

If, as we have held, the basic contribution limitations are constitutionally
valid, then surely these provisions are a constitutionally acceptable
accommodation of Congress' valid interest in encouraging citizen
participation in political campaigns while continuing to guard against the
corrupting potential of large financial contributions to candidates. The
expenditure of resources at the candidate's direction for a fundraising
event at a volunteer's residence or the provision of in-kind assistance in
the form of food or beverages to be resold to raise funds or consumed
by the participants in such an event provides material financial assistance
to a candidate. The ultimate [424 U.S. 1, 37]  effect is the same as if the
person had contributed the dollar amount to the candidate and the
candidate had then used the contribution to pay for the fundraising event
or the food. Similarly, travel undertaken as a volunteer at the direction of
the candidate or his staff is an expense of the campaign and may
properly be viewed as a contribution if the volunteer absorbs the fare.
Treating these expenses as contributions when made to the candidate's
campaign or at the direction of the candidate or his staff forecloses an
avenue of abuse [42] without limiting actions voluntarily undertaken by
citizens independently of a candidate's campaign. [43]  [424 U.S. 1, 38] 

4. The $25,000 Limitation on Total Contributions During any Calendar
Year

In addition to the $1,000 limitation on the nonexempt contributions that
an individual may make to a particular candidate for any single election,
the Act contains an overall $25,000 limitation on total contributions by
an individual during any calendar year. 608 (b) (3). A contribution made
in connection with an election is considered, for purposes of this
subsection, to be made in the year the election is held. Although the
constitutionality of this provision was drawn into question by appellants,
it has not been separately addressed at length by the parties. The overall
$25,000 ceiling does impose an ultimate restriction upon the number of
candidates and committees with which an individual may associate
himself by means of financial support. But this quite modest restraint
upon protected political activity serves to prevent evasion of the $1,000
contribution limitation by a person who might otherwise contribute
massive amounts of money to a particular candidate through the use of
unearmarked contributions to political committees likely to contribute to
that candidate, or huge contributions to the candidate's political party.
The limited, additional restriction on associational freedom imposed by
the overall ceiling is thus no more than a corollary of the basic individual
contribution limitation that we have found to be constitutionally valid. [424
U.S. 1, 39] 

     C. Expenditure Limitations 

The Act's expenditure ceilings impose direct and substantial restraints on
the quantity of political speech. The most drastic of the limitations
restricts individuals and groups, including political parties that fail to
place a candidate on the ballot,[44] to an expenditure of $1,000 "relative
to a clearly identified candidate during a calendar year." 608 (e) (1).
Other expenditure ceilings limit spending by candidates, 608 (a), their
campaigns, 608 (c), and political parties in connection with election
campaigns, 608 (f). It is clear that a primary effect of these expenditure
limitations is to restrict the quantity of campaign speech by individuals,
groups, and candidates. The restrictions, while neutral as to the ideas
expressed, limit political expression "at the core of our electoral process
and of the First Amendment freedoms." Williams v. Rhodes, 393 U.S.
23, 32 (1968).

1. The $1,000 Limitation on Expenditures "Relative to a Clearly
Identified Candidate"

Section 608 (e) (1) provides that "[n]o person may make any
expenditure ... relative to a clearly identified candidate during a calendar
year which, when added to all other expenditures made by such person
during the year advocating the election or defeat of such candidate,
exceeds $1,000." [45] The plain effect of 608 (e) (1) is to [424 U.S. 1, 40] 
prohibit all individuals, who are neither candidates nor owners of
institutional press facilities, and all groups, except political parties and
campaign organizations, from voicing their views "relative to a clearly
identified candidate" through means that entail aggregate expenditures of
more than $1,000 during a calendar year. The provision, for example,
would make it a federal criminal offense for a person or association to
place a single one-quarter page advertisement "relative to a clearly
identified candidate" in a major metropolitan newspaper.[46 ] 

Before examining the interests advanced in support of 608 (e) (1)'s
expenditure ceiling, consideration must be given to appellants' contention
that the provision is unconstitutionally vague.[47] Close examination of
the [424 U.S. 1, 41]   specificity of the statutory limitation is required where,
as here, the legislation imposes criminal penalties in an area permeated
by First Amendment interests. See Smith v. Goguen, 415 U.S. 566, 573
(1974); Cramp v. Board of Public Instruction, 368 U.S. 278, 287 -288
(1961); Smith v. California, 361 U.S. 147, 151 (1959).[48] The test is
whether the language of 608 (e) (1) affords the "[p]recision of regulation
[that] must be the touchstone in an area so closely touching our most
precious freedoms." NAACP v. Button, 371 U.S., at 438 .

The key operative language of the provision limits "any expenditure . . .
relative to a clearly identified candidate." Although "expenditure," "clearly
identified," and "candidate" are defined in the Act, there is no definition
clarifying what expenditures are "relative to" a candidate. The use of so
indefinite a phrase as "relative to" a candidate fails to clearly mark the
boundary between permissible and impermissible speech, unless other
portions of 608 (e) (1) make sufficiently explicit the range of
expenditures [424 U.S. 1, 42]  covered by the limitation. The section
prohibits "any expenditure ... relative to a clearly identified candidate
during a calendar year which, when added to all other expenditures ...
advocating the election or defeat of such candidate, exceeds $1,000."
(Emphasis added.) This context clearly permits, if indeed it does not
require, the phrase "relative to" a candidate to be read to mean
"advocating the election or defeat of" a candidate. [49] 

But while such a construction of 608 (e) (1) refocuses the vagueness
question, the Court of Appeals was mistaken in thinking that this
construction eliminates the problem of unconstitutional vagueness
altogether. 171 U.S. App. D.C., at 204, 519 F.2d, at 853. For the
distinction between discussion of issues and candidates and advocacy of
election or defeat of candidates may often dissolve in practical
application. Candidates, especially incumbents, are intimately tied to
public issues involving legislative proposals and governmental actions.
Not only do candidates campaign on the basis of their positions on
various public issues, but campaigns themselves generate issues of public
interest.[50] In an analogous [424 U.S. 1, 43]  context, this Court in Thomas
v. Collins, 323 U.S. 516 (1945), observed:

     "[W]hether words intended and designed to fall short of invitation
     would miss that mark is a question both of intent and of effect. No
     speaker, in such circumstances, safely could assume that anything
     he might say upon the general subject would not be understood
     by some as an invitation. In short, the supposedly clear-cut
     distinction between discussion, laudation, general advocacy, and
     solicitation puts the speaker in these circumstances wholly at the
     mercy of the varied understanding of his hearers and consequently
     of whatever inference may be drawn as to his intent and meaning. 

     "Such a distinction offers no security for free discussion. In these
     conditions it blankets with uncertainty whatever may be said. It
     compels the speaker to hedge and trim." Id., at 535. 

See also United States v. Auto. Workers, 352 U.S. 567, 595 -596
(1957) (Douglas, J., dissenting); Gitlow v. New York, 268 U.S. 652,
673 (1925) (Holmes, J., dissenting).

The constitutional deficiencies described in Thomas v. Collins can be
avoided only by reading 608 (e) (1) as limited to communications that
include explicit words of advocacy of election or defeat of a candidate,
much as the definition of "clearly identified" in 608 (e) (2) requires that
an explicit and unambiguous reference to the candidate appear as part of
the communication.[51] This [424 U.S. 1, 44]  is the reading of the provision
suggested by the non-governmental appellees in arguing that "[f]unds
spent to propagate one's views on issues without expressly calling for a
candidate's election or defeat are thus not covered." We agree that in
order to preserve the provision against invalidation on vagueness
grounds, 608 (e) (1) must be construed to apply only to expenditures for
communications that in express terms advocate the election or defeat of
a clearly identified candidate for federal office.[52] 

We turn then to the basic First Amendment question -- whether 608 (e)
(1), even as thus narrowly and explicitly construed, impermissibly
burdens the constitutional right of free expression. The Court of Appeals
summarily held the provision constitutionally valid on the ground that
"section 608 (e) is a loophole-closing provision only" that is necessary to
prevent circumvention of the contribution limitations. 171 U.S. App.
D.C., at 204, 519 F.2d, at 853. We cannot agree.

The discussion in Part I-A, supra, explains why the Act's expenditure
limitations impose far greater restraints on the freedom of speech and
association than do its contribution limitations. The markedly greater
burden on basic freedoms caused by 608 (e) (1) thus cannot be
sustained simply by invoking the interest in maximizing the effectiveness
of the less intrusive contribution limitations. Rather, the constitutionality
of 608 (e) (1) turns on whether the governmental interests advanced in
its support satisfy the exacting scrutiny applicable to limitations [424 U.S. 1,
45]  on core First Amendment rights of political expression. 

We find that the governmental interest in preventing corruption and the
appearance of corruption is inadequate to justify 608 (e) (1)'s ceiling on
independent expenditures. First, assuming, arguendo, that large
independent expenditures pose the same dangers of actual or apparent
quid pro quo arrangements as do large contributions, 608 (e) (1) does
not provide an answer that sufficiently relates to the elimination of those
dangers. Unlike the contribution limitations' total ban on the giving of
large amounts of money to candidates, 608 (e) (1) prevents only some
large expenditures. So long as persons and groups eschew expenditures
that in express terms advocate the election or defeat of a clearly
identified candidate, they are free to spend as much as they want to
promote the candidate and his views. The exacting interpretation of the
statutory language necessary to avoid unconstitutional vagueness thus
undermines the limitation's effectiveness as a loophole-closing provision
by facilitating circumvention by those seeking to exert improper influence
upon a candidate or office-holder. It would naively underestimate the
ingenuity and resourcefulness of persons and groups desiring to buy
influence to believe that they would have much difficulty devising
expenditures that skirted the restriction on express advocacy of election
or defeat but nevertheless benefited the candidate's campaign. Yet no
substantial societal interest would be served by a loophole-closing
provision designed to check corruption that permitted unscrupulous
persons and organizations to expend unlimited sums of money in order
to obtain improper influence over candidates for elective office. Cf. Mills
v. Alabama, 384 U.S., at 220 .

Second, quite apart from the shortcomings of 608 (e) [424 U.S. 1, 46]  (1)
in preventing any abuses generated by large independent expenditures,
the independent advocacy restricted by the provision does not presently
appear to pose dangers of real or apparent corruption comparable to
those identified with large campaign contributions. The parties defending
608 (e) (1) contend that it is necessary to prevent would-be contributors
from avoiding the contribution limitations by the simple expedient of
paying directly for media advertisements or for other portions of the
candidate's campaign activities. They argue that expenditures controlled
by or coordinated with the candidate and his campaign might well have
virtually the same value to the candidate as a contribution and would
pose similar dangers of abuse. Yet such controlled or coordinated
expenditures are treated as contributions rather than expenditures under
the Act. [53] Section 608 (b)'s [424 U.S. 1, 47]  contribution ceilings rather
than 608 (e) (1)'s independent expenditure limitation prevent attempts to
circumvent the Act through prearranged or coordinated expenditures
amounting to disguised contributions. By contrast, 608 (e) (1) limits
expenditures for express advocacy of candidates made totally
independently of the candidate and his campaign. Unlike contributions,
such independent expenditures may well provide little assistance to the
candidate's campaign and indeed may prove counterproductive. The
absence of prearrangement and coordination of an expenditure with the
candidate or his agent not only undermines the value of the expenditure
to the candidate, but also alleviates the danger that expenditures will be
given as a quid pro quo for improper commitments from the candidate.
Rather than preventing circumvention of the contribution limitations, 608
(e) (1) severely restricts all independent advocacy despite its
substantially diminished potential for abuse.

While the independent expenditure ceiling thus fails to serve any
substantial governmental interest in stemming [424 U.S. 1, 48]  the reality or
appearance of corruption in the electoral process, it heavily burdens
core First Amendment expression. For the First Amendment right to
"`speak one's mind ... on all public institutions'" includes the right to
engage in "`vigorous advocacy' no less than `abstract discussion.'" New
York Times Co. v. Sullivan, 376 U.S., at 269 , quoting Bridges v.
California, 314 U.S. 252, 270 (1941), and NAACP v. Button, 371
U.S., at 429. Advocacy of the election or defeat of candidates for
federal office is no less entitled to protection under the First Amendment
than the discussion of political policy generally or advocacy of the
passage or defeat of legislation.[54] 

It is argued, however, that the ancillary governmental interest in
equalizing the relative ability of individuals and groups to influence the
outcome of elections serves to justify the limitation on express advocacy
of the election or defeat of candidates imposed by 608 (e) (1)'s
expenditure ceiling. But the concept that government may restrict the
speech of some elements of our society in [424 U.S. 1, 49]   order to
enhance the relative voice of others is wholly foreign to the First
Amendment, which was designed "to secure `the widest possible
dissemination of information from diverse and antagonistic sources,'" and
"`to assure unfettered interchange of ideas for the bringing about of
political and social changes desired by the people.'" New York Times
Co. v. Sullivan, supra, at 266, 269, quoting Associated Press v. United
States, 326 U.S. 1, 20 (1945), and Roth v. United States, 354 U.S., at
484 . The First Amendment's protection against governmental
abridgment of free expression cannot properly be made to depend on a
person's financial ability to engage in public discussion. Cf. Eastern R.
Conf. v. Noerr Motors, 365 U.S. 127, 139 (1961).[55]  [424 U.S. 1, 50] 

The Court's decisions in Mills v. Alabama, 384 U.S. 214 (1966), and
Miami Herald Publishing Co. v. Tornillo, 418 U.S. 241 (1974), held that
legislative restrictions on advocacy of the election or defeat of political
candidates are wholly at odds with the guarantees of the First
Amendment. In Mills, the Court addressed the question whether "a
State, consistently with the United States Constitution, can make it a
crime for the editor of a daily newspaper to write and publish an editorial
on election day urging people to vote a certain way on issues submitted
to them." 384 U.S., at 215 (emphasis in original). We held that "no test
of reasonableness can save [such] a state law from invalidation as a
violation of the First Amendment." Id., at 220. Yet the prohibition of
election-day editorials invalidated in Mills is clearly a lesser intrusion on
constitutional freedom than a $1,000 limitation on the amount of money
any person or association can spend during an entire election year in
advocating the election or defeat of a candidate for public office. More
recently in Tornillo, the Court held that Florida could not constitutionally
require a newspaper [424 U.S. 1, 51]  to make space available for a
political candidate to reply to its criticism. Yet under the Florida statute,
every newspaper was free to criticize any candidate as much as it
pleased so long as it undertook the modest burden of printing his reply.
See 418 U.S., at 256-257. The legislative restraint involved in Tornillo
thus also pales in comparison to the limitations imposed by 608 (e) (1).
[56] 

For the reasons stated, we conclude that 608 (e) (1)'s independent
expenditure limitation is unconstitutional under the First Amendment.

2. Limitation on Expenditures by Candidates from Personal or Family
Resources

The Act also sets limits on expenditures by a candidate "from his
personal funds, or the personal funds of his immediate family, in
connection with his campaigns during any calendar year." 608 (a) (1).
These ceilings vary from $50,000 for Presidential or Vice Presidential
candidates to $35,000 for senatorial candidates, and $25,000 for most
candidates for the House of Representatives.[57]  [424 U.S. 1, 52] 

The ceiling on personal expenditures by candidates on their own behalf,
like the limitations on independent expenditures contained in 608 (e) (1),
imposes a substantial restraint on the ability of persons to engage in
protected First Amendment expression.[58] The candidate, no less than
any other person, has a First Amendment right to engage in the
discussion of public issues and vigorously and tirelessly to advocate his
own election and the election of other candidates. Indeed, it is of
particular importance that candidates have the unfettered [424 U.S. 1, 53]  
opportunity to make their views known so that the electorate may
intelligently evaluate the candidates' personal qualities and their positions
on vital public issues before choosing among them on election day. Mr.
Justice Brandeis' observation that in our country "public discussion is a
political duty," Whitney v. California, 274 U.S. 357, 375 (1927)
(concurring opinion), applies with special force to candidates for public
office. Section 608 (a)'s ceiling on personal expenditures by a candidate
in furtherance of his own candidacy thus clearly and directly interferes
with constitutionally protected freedoms.

The primary governmental interest served by the Act -- the prevention of
actual and apparent corruption of the political process -- does not
support the limitation on the candidate's expenditure of his own personal
funds. As the Court of Appeals concluded: "Manifestly, the core
problem of avoiding undisclosed and undue influence on candidates from
outside interests has lesser application when the monies involved come
from the candidate himself or from his immediate family." 171 U.S. App.
D.C., at 206, 519 F.2d, at 855. Indeed, the use of personal funds
reduces the candidate's dependence on outside contributions and
thereby counteracts the coercive pressures and attendant risks of abuse
to which the Act's contribution limitations are directed. [59]  [424 U.S. 1,
54] 

The ancillary interest in equalizing the relative financial resources of
candidates competing for elective office, therefore, provides the sole
relevant rationale for 608 (a)'s expenditure ceiling. That interest is clearly
not sufficient to justify the provision's infringement of fundamental First
Amendment rights. First, the limitation may fail to promote financial
equality among candidates. A candidate who spends less of his personal
resources on his campaign may nonetheless outspend his rival as a result
of more successful fundraising efforts. Indeed, a candidate's personal
wealth may impede his efforts to persuade others that he needs their
financial contributions or volunteer efforts to conduct an effective
campaign. Second, and more fundamentally, the First Amendment
simply cannot tolerate 608 (a)'s restriction upon the freedom of a
candidate to speak without legislative limit on behalf of his own
candidacy. We therefore hold that 608 (a)'s restriction on a candidate's
personal expenditures is unconstitutional.

3. Limitations on Campaign Expenditures

Section 608 (c) places limitations on overall campaign expenditures by
candidates seeking nomination for election and election to federal office.
[60] Presidential candidates may spend $10,000,000 in seeking
nomination for office and an additional $20,000,000 in the general
election campaign. 608 (c) (1) (A), (B).[61 ]  [424 U.S. 1, 55]  The ceiling
on senatorial campaigns is pegged to the size of the voting-age
population of the State with minimum dollar amounts applicable to
campaigns in States with small populations. In senatorial primary
elections, the limit is the greater of eight cents multiplied by the
voting-age population or $100,000, and in the general election the limit
is increased to 12 cents multiplied by the voting-age population or
$150,000. 608 (c) (1) (C), (D). The Act imposes blanket $70,000
limitations on both primary campaigns and general election campaigns
for the House of Representatives with the exception that the senatorial
ceiling applies to campaigns in States entitled to only one Representative.
608 (c) (1) (C)-(E). These ceilings are to be adjusted upwards at the
beginning of each calendar year by the average percentage rise in the
consumer price index for the 12 preceding months. 608 (d). [62] 

No governmental interest that has been suggested is sufficient to justify
the restriction on the quantity of political expression imposed by 608
(c)'s campaign expenditure limitations. The major evil associated with
rapidly increasing campaign expenditures is the danger of candidate
dependence on large contributions. The interest in alleviating the
corrupting influence of large contributions is served by the Act's
contribution limitations and disclosure provisions rather than by 608 (c)'s
campaign expenditure ceilings. The Court of Appeals' assertion that the
expenditure restrictions are necessary to reduce the incentive to
circumvent direct contribution limits is not persuasive. See 171 U.S. [424
U.S. 1, 56]  App. D.C., at 210, 519 F.2d, at 859. There is no indication
that the substantial criminal penalties for violating the contribution ceilings
combined with the political repercussion of such violations will be
insufficient to police the contribution provisions. Extensive reporting,
auditing, and disclosure requirements applicable to both contributions
and expenditures by political campaigns are designed to facilitate the
detection of illegal contributions. Moreover, as the Court of Appeals
noted, the Act permits an officeholder or successful candidate to retain
contributions in excess of the expenditure ceiling and to use these funds
for "any other lawful purpose." 2 U.S.C. 439a (1970 ed., Supp. IV).
This provision undercuts whatever marginal role the expenditure
limitations might otherwise play in enforcing the contribution ceilings.

The interest in equalizing the financial resources of candidates competing
for federal office is no more convincing a justification for restricting the
scope of federal election campaigns. Given the limitation on the size of
outside contributions, the financial resources available to a candidate's
campaign, like the number of volunteers recruited, will normally vary
with the size and intensity of the candidate's support.[63] There is nothing
invidious, improper, or unhealthy in permitting such funds to be spent to
carry the candidate's message to the electorate. [64] Moreover, the
equalization of permissible campaign expenditures [424 U.S. 1, 57]  might
serve not to equalize the opportunities of all candidates, but to handicap
a candidate who lacked substantial name recognition or exposure of his
views before the start of the campaign.

The campaign expenditure ceilings appear to be designed primarily to
serve the governmental interests in reducing the allegedly skyrocketing
costs of political campaigns. Appellees and the Court of Appeals
stressed statistics indicating that spending for federal election campaigns
increased almost 300% between 1952 and 1972 in comparison with a
57.6% rise in the consumer price index during the same period.
Appellants respond that during these years the rise in campaign spending
lagged behind the percentage increase in total expenditures for
commercial advertising and the size of the gross national product. In any
event, the mere growth in the cost of federal election campaigns in and
of itself provides no basis for governmental restrictions on the quantity of
campaign spending and the resulting limitation on the scope of federal
campaigns. The First Amendment denies government the power to
determine that spending to promote one's political views is wasteful,
excessive, or unwise. In the free society ordained by our Constitution it
is not the government, but the people -- individually as citizens and
candidates and collectively as associations and political committees --
who must retain control over the quantity and range of debate on public
issues in a political campaign. [65]  [424 U.S. 1, 58] 

For these reasons we hold that 608 (c) is constitutionally invalid.[66] 

In sum, the provisions of the Act that impose a $1,000 limitation on
contributions to a single candidate, 608 (b) (1), a $5,000 limitation on
contributions by a political committee to a single candidate, 608 (b) (2),
and a $25,000 limitation on total contributions by an individual during
any calendar year, 608 (b) (3), are constitutionally valid. These
limitations, along with the disclosure provisions, constitute the Act's
primary weapons against the reality or appearance of improper influence
stemming from the dependence of candidates on large campaign
contributions. The contribution ceilings thus serve the basic governmental
interest in safeguarding the integrity of the electoral process without
directly impinging upon the rights of individual citizens and candidates to
engage in political debate and discussion. By contrast, the First
Amendment requires the invalidation of the Act's independent
expenditure ceiling, 608 (e) (1), its limitation on a candidate's
expenditures from his own personal funds, 608 (a), and its ceilings on
overall campaign expenditures, 608 (c). These provisions place
substantial and direct restrictions [424 U.S. 1, 59]   on the ability of
candidates, citizens, and associations to engage in protected political
expression, restrictions that the First Amendment cannot tolerate.[67] 
[424 U.S. 1, 60] 

     II. REPORTING AND DISCLOSURE REQUIREMENTS 

Unlike the limitations on contributions and expenditures imposed by 18
U.S.C. 608 (1970 ed., Supp. IV), the disclosure requirements of the
Act, 2 U.S.C. 431 et seq. (1970 ed., Supp. IV),[68] are not challenged
by appellants as per se unconstitutional restrictions on the exercise of
First Amendment freedoms of speech and association. [69] Indeed,
appellants argue that "narrowly drawn disclosure requirements are the
proper solution to virtually all of the evils Congress sought to remedy."
Brief for Appellants 171. The particular requirements [424 U.S. 1, 61] 
embodied in the Act are attacked as overbroad -- both in their
application to minor-party and independent candidates and in their
extension to contributions as small as $11 or $101. Appellants also
challenge the provision for disclosure by those who make independent
contributions and expenditures, 434 (e). The Court of Appeals found no
constitutional infirmities in the provisions challenged here.[70] We affirm
the determination on overbreadth and hold that 434 (e), if narrowly
construed, also is within constitutional bounds.

The first federal disclosure law was enacted in 1910. Act of June 25,
1910, c. 392, 36 Stat. 822. It required political committees, defined as
national committees and national congressional campaign committees of
parties, and organizations operating to influence congressional elections
in two or more States, to disclose names of all contributors of $100 or
more; identification of recipients of expenditures of $10 or more was
also required. 1, 5-6, 36 Stat. 822 824. Annual expenditures of $50 or
more "for the purpose of influencing or controlling, in two or more
States, the result of" a congressional election had to be reported
independently if they were not made through a political committee. 7, 36
Stat. 824. In 1911 the Act was revised to include prenomination
transactions such as those involved in conventions and primary
campaigns. Act of Aug. 19, 1911, 2, 37 Stat. 26. See United States v.
Auto. Workers, 352 U.S., at 575-576.

Disclosure requirements were broadened in the Federal Corrupt
Practices Act of 1925 (Title III of the Act of Feb. 28, 1925), 43 Stat.
1070. That Act required political committees, defined as organizations
that accept contributions or make expenditures "for the purpose of [424
U.S. 1, 62]  influencing or attempting to influence" the Presidential or Vice
Presidential elections (a) in two or more States or (b) as a subsidiary of
a national committee, 302 (c), 43 Stat. 1070, to report total
contributions and expenditures, including the names and addresses of
contributors of $100 or more and recipients of $10 or more in a
calendar year. 305 (a), 43 Stat. 1071. The Act was upheld against a
challenge that it infringed upon the prerogatives of the States in
Burroughs v. United States, 290 U.S. 534 (1934). The Court held that it
was within the power of Congress "to pass appropriate legislation to
safeguard [a Presidential] election from the improper use of money to
influence the result." Id., at 545. Although the disclosure requirements
were widely circumvented, [71] no further attempts were made to tighten
them until 1960, when the Senate passed a bill that would have closed
some existing loopholes. S. 2436, 106 Cong. Rec. 1193. The attempt
aborted because no similar effort was made in the House.

The Act presently under review replaced all prior disclosure laws. Its
primary disclosure provisions impose reporting obligations on "political
committees" and candidates. "Political committee" is defined in 431 (d)
as a group of persons that receives "contributions" or makes
"expenditures" of over $1,000 in a calendar year. "Contributions" and
"expenditures" are defined in lengthy parallel provisions similar to those
in Title 18, discussed [424 U.S. 1, 63]  above.[72] Both definitions focus on
the use of money or other objects of value "for the purpose of ...
influencing" the nomination or election of any person to federal office.
431 (e) (1), (f) (1).

Each political committee is required to register with the Commission,
433, and to keep detailed records of both contributions and
expenditures, 432 (c), (d). These records must include the name and
address of everyone making a contribution in excess of $10, along with
the date and amount of the contribution. If a person's contributions
aggregate more than $100, his occupation and principal place of
business are also to be included. 432 (c) (2). These files are subject to
periodic audits and field investigations by the Commission. 438 (a) (8).

Each committee and each candidate also is required to file quarterly
reports. 434 (a). The reports are to contain detailed financial
information, including the full name, mailing address, occupation, and
principal place of business of each person who has contributed over
$100 in a calendar year, as well as the amount and date of the
contributions. 434 (b). They are to be made available by the
Commission "for public inspection and copying." 438 (a) (4). Every
candidate for federal office is required to designate a "principal campaign
committee," which is to receive reports of contributions and expenditures
made on the candidate's behalf from other political committees and to
compile and file these reports, together with its own statements, with the
Commission. 432 (f).

Every individual or group, other than a political committee or candidate,
who makes "contributions" or "expenditures" of over $100 in a calendar
year "other than [424 U.S. 1, 64]   by contribution to a political committee
or candidate" is required to file a statement with the Commission. 434
(e). Any violation of these recordkeeping and reporting provisions is
punishable by a fine of not more than $1,000 or a prison term of not
more than a year, or both. 441 (a). 

     A. General Principles 

Unlike the overall limitations on contributions and expenditures, the
disclosure requirements impose no ceiling on campaign-related activities.
But we have repeatedly found that compelled disclosure, in itself, can
seriously infringe on privacy of association and belief guaranteed by the
First Amendment. E. g., Gibson v. Florida Legislative Comm., 372 U.S.
539 (1963); NAACP v. Button, 371 U.S. 415 (1963); Shelton v.
Tucker, 364 U.S. 479 (1960); Bates v. Little Rock, 361 U.S. 516
(1960); NAACP v. Alabama, 357 U.S. 449 (1958).

We long have recognized that significant encroachments on First
Amendment rights of the sort that compelled disclosure imposes cannot
be justified by a mere showing of some legitimate governmental interest.
Since NAACP v. Alabama we have required that the subordinating
interests of the State must survive exacting scrutiny.[73] We also have
insisted that there be a "relevant correlation"[74] or "substantial
relation"[75] between the governmental interest and the information
required to be disclosed. See Pollard v. Roberts, 283 F. Supp. 248,
257 (ED Ark.) (three-judge court), aff'd, 393 U.S. 14 (1968) [424 U.S. 1,
65]  (per curiam). This type of scrutiny is necessary even if any deterrent
effect on the exercise of First Amendment rights arises, not through
direct government action, but indirectly as an unintended but inevitable
result of the government's conduct in requiring disclosure. NAACP v.
Alabama, supra, at 461. Cf. Kusper v. Pontikes, 414 U.S., at 57-58.

Appellees argue that the disclosure requirements of the Act differ
significantly from those at issue in NAACP v. Alabama and its progeny
because the Act only requires disclosure of the names of contributors
and does not compel political organizations to submit the names of their
members. [76] 

As we have seen, group association is protected because it enhances
"[e]ffective advocacy." NAACP v. Alabama, supra, at 460. The right to
join together "for the advancement of beliefs and ideas," ibid., is diluted if
it does not include the right to pool money through contributions, for
funds are often essential if "advocacy" is [424 U.S. 1, 66]  to be truly or
optimally "effective." Moreover, the invasion of privacy of belief may be
as great when the information sought concerns the giving and spending of
money as when it concerns the joining of organizations, for "[f]inancial
transactions can reveal much about a person's activities, associations,
and beliefs." California Bankers Assn. v. Shultz, 416 U.S. 21, 78-79
(1974) (POWELL, J., concurring). Our past decisions have not drawn
fine lines between contributors and members but have treated them
interchangeably. In Bates, for example, we applied the principles of
NAACP v. Alabama and reversed convictions for failure to comply with
a city ordinance that required the disclosure of "dues, assessments, and
contributions paid, by whom and when paid." 361 U.S., at 518 . See
also United States v. Rumely, 345 U.S. 41 (1953) (setting aside a
contempt conviction of an organization official who refused to disclose
names of those who made bulk purchases of books sold by the
organization).

The strict test established by NAACP v. Alabama is necessary because
compelled disclosure has the potential for substantially infringing the
exercise of First Amendment rights. But we have acknowledged that
there are governmental interests sufficiently important to outweigh the
possibility of infringement, particularly when the "free functioning of our
national institutions" is involved. Communist Party v. Subversive
Activities Control Bd., 367 U.S. 1, 97 (1961).

The governmental interests sought to be vindicated by the disclosure
requirements are of this magnitude. They fall into three categories. First,
disclosure provides the electorate with information "as to where political
campaign money comes from and how it is spent by the candidate" [77]
in order to aid the voters in evaluating those [424 U.S. 1, 67]  who seek
federal office. It allows voters to place each candidate in the political
spectrum more precisely than is often possible solely on the basis of
party labels and campaign speeches. The sources of a candidate's
financial support also alert the voter to the interests to which a candidate
is most likely to be responsive and thus facilitate predictions of future
performance in office.

Second, disclosure requirements deter actual corruption and avoid the
appearance of corruption by exposing large contributions and
expenditures to the light of publicity.[78] This exposure may discourage
those who would use money for improper purposes either before or
after the election. A public armed with information about a candidate's
most generous supporters is better able to detect any post-election
special favors that may be given in return.[79] And, as we recognized in
Burroughs v. United States, 290 U.S., at 548, Congress could
reasonably conclude that full disclosure during an election campaign
tends "to prevent the corrupt use of money to affect elections." In
enacting these requirements it may have been mindful of Mr. Justice
Brandeis' advice:

     "Publicity is justly commended as a remedy for social and
     industrial diseases. Sunlight is said to be the best of
     disinfectants; electric light the most efficient policeman."[80]

Third, and not least significant, recordkeeping, reporting, [424 U.S. 1, 68] 
and disclosure requirements are an essential means of gathering the data
necessary to detect violations of the contribution limitations described
above.

The disclosure requirements, as a general matter, directly serve
substantial governmental interests. In determining whether these interests
are sufficient to justify the requirements we must look to the extent of the
burden that they place on individual rights.

It is undoubtedly true that public disclosure of contributions to
candidates and political parties will deter some individuals who
otherwise might contribute. In some instances, disclosure may even
expose contributors to harassment or retaliation. These are not
insignificant burdens on individual rights, and they must be weighed
carefully against the interests which Congress has sought to promote by
this legislation. In this process, we note and agree with appellants'
concession[81] that disclosure requirements -- certainly in most
applications -- appear to be the least restrictive means of curbing the
evils of campaign ignorance and corruption that Congress found to
exist.[82] Appellants argue, however, that the balance tips against
disclosure when it is required of contributors to certain parties and
candidates. We turn now to this contention. 

B. Application to Minor Parties and Independents

Appellants contend that the Act's requirements are overbroad insofar as
they apply to contributions to minor [424 U.S. 1, 69]   parties and
independent candidates because the governmental interest in this
information is minimal and the danger of significant infringement on First
Amendment rights is greatly increased.

1. Requisite Factual Showing

In NAACP v. Alabama the organization had "made an uncontroverted
showing that on past occasions revelation of the identity of its
rank-and-file members [had] exposed these members to economic
reprisal, loss of employment, threat of physical coercion, and other
manifestations of public hostility," 357 U.S., at 462 , and the State was
unable to show that the disclosure it sought had a "substantial bearing"
on the issues it sought to clarify, id., at 464. Under those circumstances,
the Court held that "whatever interest the State may have in [disclosure]
has not been shown to be sufficient to overcome petitioner's
constitutional objections." Id., at 465.

The Court of Appeals rejected appellants' suggestion that this case fits
into the NAACP v. Alabama mold. It concluded that substantial
governmental interests in "informing the electorate and preventing the
corruption of the political process" were furthered by requiring
disclosure of minor parties and independent candidates, 171 U.S. App.
D.C., at 218, 519 F.2d, at 867, and therefore found no "tenable
rationale for assuming that the public interest in minority party disclosure
of contributions above a reasonable cutoff point is uniformly outweighed
by potential contributors' associational rights," id., at 219, 519 F.2d, at
868. The court left open the question of the application of the disclosure
requirements to candidates (and parties) who could demonstrate injury
of the sort at stake in NAACP v. Alabama. No record of harassment on
a similar scale was found in this case. [83] We agree with [424 U.S. 1, 70] 
the Court of Appeals' conclusion that NAACP v. Alabama is inapposite
where, as here, any serious infringement on First Amendment rights
brought about by the compelled disclosure of contributors is highly
speculative.

It is true that the governmental interest in disclosure is diminished when
the contribution in question is made to a minor party with little chance of
winning an election. As minor parties usually represent definite and
publicized viewpoints, there may be less need to inform the voters of the
interests that specific candidates represent. Major parties encompass
candidates of greater diversity. In many situations the label "Republican"
or "Democrat" tells a voter little. The candidate who bears it may be
supported by funds from the far right, the far left, or any place in
between on the political spectrum. It is less likely that a candidate of,
say, the Socialist Labor Party will represent interests that cannot be
discerned from the party's ideological position.

The Government's interest in deterring the "buying" of elections and the
undue influence of large contributors on officeholders also may be
reduced where contributions to a minor party or an independent
candidate are concerned, for it is less likely that the candidate will be
victorious. But a minor party sometimes can play a significant role in an
election. Even when a minor-party candidate has little or no chance of
winning, he may be encouraged by major-party interests in order to
divert votes from other major-party contenders.[84]  [424 U.S. 1, 71] 

We are not unmindful that the damage done by disclosure to the
associational interests of the minor parties and their members and to
supporters of independents could be significant. These movements are
less likely to have a sound financial base and thus are more vulnerable to
falloffs in contributions. In some instances fears of reprisal may deter
contributions to the point where the movement cannot survive. The
public interest also suffers if that result comes to pass, for there is a
consequent reduction in the free circulation of ideas both within[85] and
without [86] the political arena.

There could well be a case, similar to those before the Court in NAACP
v. Alabama and Bates, where the threat to the exercise of First
Amendment rights is so serious and the state interest furthered by
disclosure so insubstantial that the Act's requirements cannot be
constitutionally applied. [87] But no appellant in this case has tendered
record evidence of the sort proffered in NAACP v. Alabama. Instead,
appellants primarily rely on "the clearly articulated fears of individuals,
well experienced in the political process." Brief for Appellants 173. At
[424 U.S. 1, 72]  best they offer the testimony of several minor-party
officials that one or two persons refused to make contributions because
of the possibility of disclosure. [88] On this record, the substantial public
interest in disclosure identified by the legislative history of this Act
outweighs the harm generally alleged.

2. Blanket Exemption

Appellants agree that "the record here does not reflect the kind of
focused and insistent harassment of contributors and members that
existed in the NAACP cases." Ibid. They argue, however, that a blanket
exemption for minor parties is necessary lest irreparable injury be done
before the required evidence can be gathered.

Those parties that would be sufficiently "minor" to be exempted from the
requirements of 434 could be defined, appellants suggest, along the lines
used for public-financing purposes, see Part III-A, infra, as those who
received less than 25% of the vote in past elections. Appellants do not
argue that this line is constitutionally required. They suggest as an
alternative defining "minor parties" as those that do not qualify for
automatic ballot access under state law. Presumably, other criteria, such
as current political strength (measured by polls or petition), age, or
degree of organization, could also be used.[89] 

The difficulty with these suggestions is that they reflect only a party's past
or present political strength and [424 U.S. 1, 73]  that is only one of the
factors that must be considered. Some of the criteria are not precisely
indicative of even that factor. Age,[90] or past political success, for
instance, may typically be associated with parties that have a high
probability of success. But not all long-established parties are winners --
some are consistent losers -- and a new party may garner a great deal of
support if it can associate itself with an issue that has captured the
public's imagination. None of the criteria suggested is precisely related to
the other critical factor that must be considered, the possibility that
disclosure will impinge upon protected associational activity.

An opinion dissenting in part from the Court of Appeals' decision
concedes that no one line is "constitutionally required." [91] It argues,
however, that a flat exemption for minor parties must be carved out,
even along arbitrary lines, if groups that would suffer impermissibly from
disclosure are to be given any real protection. An approach that requires
minor parties to submit evidence that the disclosure requirements cannot
constitutionally be applied to them offers only an illusory safeguard, the
argument goes, because the "evils" of "chill and harassment ... are largely
incapable of formal proof." [92] This dissent expressed its concern that a
minor party, particularly a [424 U.S. 1, 74]   new party, may never be able
to prove a substantial threat of harassment, however real that threat may
be, because it would be required to come forward with witnesses who
are too fearful to contribute but not too fearful to testify about their fear.
A strict requirement that chill and harassment be directly attributable to
the specific disclosure from which the exemption is sought would make
the task even more difficult.

We recognize that unduly strict requirements of proof could impose a
heavy burden, but it does not follow that a blanket exemption for minor
parties is necessary. Minor parties must be allowed sufficient flexibility in
the proof of injury to assure a fair consideration of their claim. The
evidence offered need show only a reasonable probability that the
compelled disclosure of a party's contributors' names will subject them
to threats, harassment, or reprisals from either Government officials or
private parties. The proof may include, for example, specific evidence of
past or present harassment of members due to their associational ties, or
of harassment directed against the organization itself. A pattern of threats
or specific manifestations of public hostility may be sufficient. New
parties that have no history upon which to draw may be able to offer
evidence of reprisals and threats directed against individuals or
organizations holding similar views.

Where it exists the type of chill and harassment identified in NAACP v.
Alabama can be shown. We cannot assume that courts will be
insensitive to similar showings when made in future cases. We therefore
conclude that a blanket exemption is not required.

     C. Section 434 (e) 

Section 434 (e) requires "[e]very person (other than a political
committee or candidate) who makes contributions [424 U.S. 1, 75]  or
expenditures" aggregating over $100 in a calendar year "other than by
contribution to a political committee or candidate" to file a statement with
the Commission.[93] Unlike the other disclosure provisions, this section
does not seek the contribution list of any association. Instead, it requires
direct disclosure of what an individual or group contributes or spends.

In considering this provision we must apply the same strict standard of
scrutiny, for the right of associational privacy developed in NAACP v.
Alabama derives from the rights of the organization's members to
advocate their personal points of view in the most effective way. 357
U.S., at 458, 460. See also NAACP v. Button, 371 U.S., at 429-431;
Sweezy v. New Hampshire, 354 U.S., at 250.

Appellants attack 434 (e) as a direct intrusion on privacy of belief, in
violation of Talley v. California, 362 U.S. 60 (1960), and as imposing
"very real, practical burdens ... certain to deter individuals from making
expenditures for their independent political speech" analogous to those
held to be impermissible in Thomas v. Collins, 323 U.S. 516 (1945).

1. The Role of 434 (e)

The Court of Appeals upheld 434 (e) as necessary to enforce the
independent-expenditure ceiling imposed by 18 U.S.C. 608 (e) (1)
(1970 ed., Supp. IV). It said:

     "If ... Congress has both the authority and a compelling interest to
     regulate independent expenditures under section 608 (e), surely it
     can require that there be disclosure to prevent misuse of the
     spending channel." 171 U.S. App. D.C., at 220 519 F.2d, at
     869. 

We have found that 608 (e) (1) unconstitutionally infringes [424 U.S. 1, 76] 
upon First Amendment rights. [94] If the sole function of 434 (e) were to
aid in the enforcement of that provision, it would no longer serve any
governmental purpose.

But the two provisions are not so intimately tied. The legislative history
on the function of 434 (e) is bare, but it was clearly intended to stand
independently of 608 (e) (1). It was enacted with the general disclosure
provisions in 1971 as part of the original Act,[95 ] while 608 (e) (1) was
part of the 1974 amendments. [96] Like the other disclosure provisions,
434 (e) could play a role in the enforcement of the expanded
contribution and expenditure limitations included in the 1974
amendments, but it also has independent functions. Section 434 (e) is
part of Congress' effort to achieve "total disclosure" by reaching "every
kind of political activity"[97] in order to insure that the voters are fully
informed and to achieve through publicity the maximum deterrence to
corruption and undue influence possible. The provision is responsive to
the legitimate fear that efforts would be made, as they had been in the
past,[98] to avoid the disclosure requirements by routing financial
support of candidates through avenues not explicitly covered by the
general provisions of the Act.

2. Vagueness Problems

In its effort to be all-inclusive, however, the provision raises serious
problems of vagueness, particularly treacherous where, as here, the
violation of its terms carries criminal penalties[99] and fear of incurring
these sanctions [424 U.S. 1, 77]  may deter those who seek to exercise
protected First Amendment rights.

Section 434 (e) applies to "[e]very person ... who makes contributions
or expenditures." "Contributions" and "expenditures" are defined in
parallel provisions in terms of the use of money or other valuable assets
"for the purpose of ... influencing" the nomination or election of
candidates for federal office.[100] It is the ambiguity of this phrase that
poses constitutional problems.

Due process requires that a criminal statute provide adequate notice to a
person of ordinary intelligence that his contemplated conduct is illegal,
for "no man shall be held criminally responsible for conduct which he
could not reasonably understand to be proscribed." United States v.
Harriss, 347 U.S. 612, 617 (1954). See also Papachristou v. City of
Jacksonville, 405 U.S. 156 (1972). Where First Amendment rights are
involved, an even "greater degree of specificity" is required. Smith v.
Goguen, 415 U.S., at 573. See Grayned v. City of Rockford, 408 U.S.
104, 109 (1972); Kunz v. New York, 340 U.S. 290 (1951).

There is no legislative history to guide us in determining the scope of the
critical phrase "for the purpose of ... influencing." It appears to have
been adopted without comment from earlier disclosure Acts. [101]
Congress "has voiced its wishes in [most] muted strains," leaving us to
draw upon "those common-sense assumptions that must be made in
determining direction without a compass." Rosado v. Wyman, 397 U.S.
397, 412 (1970). Where the constitutional requirement of definiteness is
at stake, we have the further obligation to construe the statute, [424 U.S. 1,
78]  if that can be done consistent with the legislature's purpose, to avoid
the shoals of vagueness. United States v. Harriss, supra, at 618; United
States v. Rumely, 345 U.S., at 45.

In enacting the legislation under review Congress addressed broadly the
problem of political campaign financing. It wished to promote full
disclosure of campaign-oriented spending to insure both the reality and
the appearance of the purity and openness of the federal election
process. [102] Our task is to construe "for the purpose of ... influencing,"
incorporated in 434 (e) through the definitions of "contributions" and
"expenditures," in a manner that precisely furthers this goal.

In Part I we discussed what constituted a "contribution" for purposes of
the contribution limitations set forth in 18 U.S.C. 608 (b) (1970 ed.,
Supp. IV).[103] We construed that term to include not only contributions
made directly or indirectly to a candidate, political party, or campaign
committee, and contributions made to other organizations or individuals
but earmarked for political purposes, but also all expenditures placed in
cooperation with or with the consent of a candidate, his agents, or an
authorized committee of the candidate. The definition of "contribution" in
431 (e) for disclosure purposes parallels the definition in Title 18 almost
word for word, and we construe the former provision as we have the
latter. So defined, "contributions" have a sufficiently close relationship to
the goals of the Act, for they are connected with a candidate or his
campaign.

When we attempt to define "expenditure" in a similarly narrow way we
encounter line-drawing problems [424 U.S. 1, 79]  of the sort we faced in
18 U.S.C. 608 (e) (1) (1970 ed., Supp. IV). Although the phrase, "for
the purpose of ... influencing" an election or nomination, differs from the
language used in 608 (e) (1), it shares the same potential for
encompassing both issue discussion and advocacy of a political
result.[104] The general requirement that "political committees" and
candidates disclose their expenditures could raise similar vagueness
problems, for "political committee" is defined only in terms of amount of
annual "contributions" and "expenditures," [105] and could be interpreted
to reach groups engaged purely in issue discussion. The lower courts
have construed the words "political committee" more narrowly.[106 ] To
fulfill the purposes of the Act they need only encompass organizations
that are under the control of a candidate or the major purpose of which
is the nomination or election of a candidate. Expenditures of candidates
and of "political committees" so construed can be assumed to fall within
the core area sought to be addressed by Congress. They are, by
definition, campaign related.

But when the maker of the expenditure is not within these categories --
when it is an individual other than a candidate or a group other than a
"political committee"[107]  [424 U.S. 1, 80]  -- the relation of the information
sought to the purposes of the Act may be too remote. To insure that the
reach of 434 (e) is not impermissibly broad, we construe "expenditure"
for purposes of that section in the same way we construed the terms of
608 (e) -- to reach only funds used for communications that expressly
advocate[108] the election or defeat of a clearly identified candidate.
This reading is directed precisely to that spending that is unambiguously
related to the campaign of a particular federal candidate.

In summary, 434 (e), as construed, imposes independent reporting
requirements on individuals and groups that are not candidates or
political committees only in the following circumstances: (1) when they
make contributions earmarked for political purposes or authorized or
requested by a candidate or his agent, to some person other than a
candidate or political committee, and (2) when they make expenditures
for communications that expressly advocate the election or defeat of a
clearly identified candidate. 

Unlike 18 U.S.C. 608 (e) (1) (1970 ed., Supp. IV), 434 (e), as
construed, bears a sufficient relationship to a substantial governmental
interest. As narrowed, 434 (e), like 608 (e) (1), does not reach all
partisan discussion for it only requires disclosure of those expenditures
that expressly advocate a particular election result. This might have been
fatal if the only purpose of 434 (e) [424 U.S. 1, 81]  were to stem
corruption or its appearance by closing a loophole in the general
disclosure requirements. But the disclosure provisions, including 434 (e),
serve another, informational interest, and even as construed 434 (e)
increases the fund of information concerning those who support the
candidates. It goes beyond the general disclosure requirements to shed
the light of publicity on spending that is unambiguously campaign related
but would not otherwise be reported because it takes the form of
independent expenditures or of contributions to an individual or group
not itself required to report the names of its contributors. By the same
token, it is not fatal that 434 (e) encompasses purely independent
expenditures uncoordinated with a particular candidate or his agent. The
corruption potential of these expenditures may be significantly different,
but the informational interest can be as strong as it is in coordinated
spending, for disclosure helps voters to define more of the candidates'
constituencies.

Section 434 (e), as we have construed it, does not contain the infirmities
of the provisions before the Court in Talley v. California, 362 U.S. 60
(1960), and Thomas v. Collins, 323 U.S. 516 (1945). The ordinance
found wanting in Talley forbade all distribution of handbills that did not
contain the name of the printer, author, or manufacturer, and the name of
the distributor. The city urged that the ordinance was aimed at identifying
those responsible for fraud, false advertising, and libel, but the Court
found that it was "in no manner so limited." 362 U.S., at 64 . Here, as
we have seen, the disclosure requirement is narrowly limited to those
situations where the information sought has a substantial connection with
the governmental interests sought to be advanced. Thomas held
unconstitutional a prior restraint in the form of a registration requirement
for labor organizers. [424 U.S. 1, 82]  The Court found the State's interest
insufficient to justify the restrictive effect of the statute. The burden
imposed by 434 (e) is no prior restraint, but a reasonable and minimally
restrictive method of furthering First Amendment values by opening the
basic processes of our federal election system to public view.[109] 

     D. Thresholds 

Appellants' third contention, based on alleged overbreadth, is that the
monetary thresholds in the recordkeeping and reporting provisions lack
a substantial nexus with the claimed governmental interests, for the
amounts involved are too low even to attract the attention of the
candidate, much less have a corrupting influence.

The provisions contain two thresholds. Records are to be kept by
political committees of the names and addresses of those who make
contributions in excess of $10, 432 (c) (2), and these records are
subject to Commission audit, 438 (a) (8). If a person's contributions to a
committee or candidate aggregate more than $100, his name and
address, as well as his occupation and principal place of business, are to
be included in reports filed by committees and candidates with the
Commission, 434 (b) (2), and made available for public inspection, 438
(a) (4).

The Court of Appeals rejected appellants' contention that these
thresholds are unconstitutional. It found the challenge on First
Amendment grounds to the $10 threshold to be premature, for it could
"discern no basis in the statute for authorizing disclosure outside the
Commission [424 U.S. 1, 83]  ..., and hence no substantial `inhibitory effect'
operating upon" appellants. 171 U.S. App. D.C., at 216, 519 F.2d, at
865. The $100 threshold was found to be within the "reasonable
latitude" given the legislature "as to where to draw the line." Ibid. We
agree.

The $10 and $100 thresholds are indeed low. Contributors of relatively
small amounts are likely to be especially sensitive to recording or
disclosure of their political preferences. These strict requirements may
well discourage participation by some citizens in the political process, a
result that Congress hardly could have intended. Indeed, there is little in
the legislative history to indicate that Congress focused carefully on the
appropriate level at which to require recording and disclosure. Rather, it
seems
