stitutional 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

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

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 candiClassic, 313 U. S. 299 (1941). The Court has also recognized broad
congressional power to legislate in connection with the elections of
the President and Vice President. Burroughs v. United States, 290
U. S. 534 (1934). See Part III, infra.
