OCTOBER TERM, 1975
Per Curiam
424 U. S.
tion 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.
Senator Charles Mathias, Jr., operated large-scale campaigns on
contributions raised under a voluntarily imposed $100 contribution
limitation.
