Which campaign-contribution limits remained in effect after McCutcheon v. Federal Election Commission?

In the 2014 case McCutcheon v. Federal Election Commission, the U.S. Supreme Court struck down aggregate limits on the total amount an individual could contribute to all federal candidates, party committees, and political action committees (PACs) during a two-year election cycle.1

However, the ruling did not affect the so-called "base limits," which remained in effect. These regulations, established under the Federal Election Campaign Act (FECA), include:1

• Individual to Candidate: Limits on contributions by individuals to a single candidate per election.21
• Individual to National Party Committee: Limits on annual contributions by individuals to national party committees.21
• Individual to PAC: Limits on annual contributions by individuals to noncandidate political action committees.21

These base limits were not at issue in the McCutcheon case, as the court focused specifically on the constitutionality of aggregate caps under the First Amendment.1
