Contributions can signal intensity, help a group build a relationship, and fund campaign activity. They do not lawfully purchase an official act. Campaign-finance doctrine permits regulation aimed at quid pro quo corruption or its appearance while protecting political speech and association. Earmarking rules prevent a donor from evading a candidate-contribution limit by routing money through an intermediary, and disclosure can reveal sources and spending. A contribution may lead to access or gratitude without proving an illegal bargain; evidence of an actual exchange is a different matter.

The Supreme Court's 2026 decision in National Republican Senatorial Committee v. FEC created an important, narrow update. The Court invalidated FECA's special limits on political-party coordinated expenditures under 52 U.S.C. 30116(d), which applied to party spending coordinated with federal general-election candidates. It reasoned that base contribution limits, earmarking rules, and disclosure offered more targeted ways to address circumvention. The decision did not invalidate all limits on contributions to candidates, erase earmarking or disclosure rules, or give nonparty interest groups a general right to coordinate unlimited spending.

Imagine three transactions. A traditional PAC transfers funds to a candidate committee: that is a regulated contribution. An outside organization purchases its own advertisement without consulting the campaign: that may be an independent expenditure. A national party consults its federal general-election candidate about an advertisement's content and placement: it is a political-party coordinated expenditure, and the special Section 30116(d) caps challenged in the 2026 case are unconstitutional. Spender, recipient, control, coordination, and statutory category still matter; the party-specific holding did not erase every campaign-finance distinction.
