Syllabus
the actual corruption threatened by large financial contributions and
the eroding of public confidence in the electoral process through the
appearance of corruption." E.g., Federal Election Comm'n v. National Right to Work Comm., 459 U. S. 197, 208. The less rigorous
review standard shows proper deference to Congress' ability to weigh
competing constitutional interests in an area in which it enjoys particular expertise, and provides it with sufficient room to anticipate
and respond to concerns about circumvention of regulations designed to
protect the political process' integrity. Finally, because Congress, in
its lengthy deliberations leading to BCRA's enactment, properly relied
on Buckley and its progeny, stare decisis considerations, buttressed
by the respect that the Legislative and Judicial Branches owe one another, provide additional powerful reasons for adhering to the analysis
of contribution limits the Court has consistently followed since Buckley.
The Court rejects plaintiffs' argument that the type of speech and
associational burdens that § 323 imposes are fundamentally different from the burdens that accompanied Buckley's contribution limits.
Pp. 134-142.
(b) New FECA § 323(a)-which forbids national party committees
and their agents to "solicit, receive .... direct..., or spend any funds,
that are not subject to [FECA's] limitations, prohibitions, and reporting requirements," 2 U. S. C. § 441i(a)(1)--does not violate the First
Amendment. Pp. 142-161.
(1) The governmental interest underlying §323(a)-preventing
the actual or apparent corruption of federal candidates and officeholders-constitutes a sufficiently important interest to justify contribution
limits. That interest is not limited to the elimination of quid pro quo,
cash-for-votes exchanges, see Buckley, supra, at 28, but extends also to
"undue influence on an officeholder's judgment, and the appearance of
such influence," FederalElection Comm'n v. Colorado Republican Federal Campaign Comm., 533 U. S.431, 441 (Colorado II). These interests are sufficient to justify not only contribution limits themselves, but
also laws preventing the circumvention of such limits. Id., at 456.
While the quantum of empirical evidence needed to satisfy heightened
judicial scrutiny of legislative judgments varies with the novelty or
plausibility of the justification raised, Nixon v. Shrink Missouri Government PAC, 528 U. S. 377, 391, the idea that large contributions to a
national party can corrupt or create the appearance of corruption of
federal candidates and officeholders is neither novel nor implausible, see,
e. g., Buckley, supra, at 38. There is substantial evidence in these cases
to support Congress' determination that such contributions of soft
money give rise to corruption and the appearance of corruption. For
instance, the record is replete with examples of national party commit-
