What level of First Amendment scrutiny applies to the aggregate limits on political contributions?
Holding
The Court applied Buckley’s “closely drawn” standard for contribution limits and held that the aggregate limits fail even that standard; it therefore did not decide whether strict scrutiny should apply.
Reasoning
Buckley v. Valeo distinguishes contribution limits from expenditure limits. Although both implicate core political expression and association, Buckley treated contribution limits as imposing a comparatively lesser burden and allowed them only when they serve a sufficiently important governmental interest through means closely drawn to avoid unnecessary abridgment of associational freedoms.
The Court did not revisit Buckley’s contribution-expenditure distinction because the result did not depend on choosing between strict scrutiny and the closely drawn test. Under either formulation, the Court had to assess the fit between the Government’s anticorruption objective and the aggregate limits’ broad restriction on political participation.
The aggregate cap did more than regulate the amount a person could give to a particular candidate. Once a donor reached the cap, it prohibited any further contribution—even a small contribution to another candidate or cause that remained well below every applicable base limit. The Court regarded that as a serious burden on political expression and association, particularly for donors seeking to support a wide range of candidates and policy concerns.
