40 MCCUTCHEON v. FEDERAL ELECTION COMM’N Opinion of ROBERTS, C. J. aggregate limits on contributions do not further the only governmental interest this Court accepted as legitimate in Buckley. They instead intrude without justification on a citizen’s ability to exercise “the most fundamental First Amendment activities.” Buckley, 424 U. S., at 14. The judgment of the District Court is reversed, and the case is remanded for further proceedings. It is so ordered.
