10 MCCUTCHEON v. FEDERAL ELECTION COMM’N Opinion of ROBERTS, C. J. B 1 The parties and amici curiae spend significant energy debating whether the line that Buckley drew between contributions and expenditures should remain the law. Notwithstanding the robust debate, we see no need in this case to revisit Buckley’s distinction between contributions and expenditures and the corollary distinction in the applicable standards of review. Buckley held that the Government’s interest in preventing quid pro quo corruption or its appearance was “sufficiently important,” id., at 26–27; we have elsewhere stated that the same interest may properly be labeled “compelling,” see National Conservative Political Action Comm., 470 U. S., at 496–497, so that the interest would satisfy even strict scrutiny. Moreover, regardless whether we apply strict scrutiny or Buckley’s “closely drawn” test, we must assess the fit between the stated governmental objective and the means selected to achieve that objective. See, e.g., National Conservative Political Action Comm., supra, at 496–501; Randall v. Sorrell, 548 U. S. 230, 253–262 (2006) (opinion of BREYER, J.). Or to put it another way, if a law that restricts political speech does not “avoid unnecessary abridgement” of First Amendment rights, Buckley, 424 U. S., at 25, it cannot survive “rigorous” review. Because we find a substantial mismatch between the Government’s stated objective and the means selected to achieve it, the aggregate limits fail even under the “closely drawn” test. We therefore need not parse the differences between the two standards in this case. 2 Buckley treated the constitutionality of the $25,000 aggregate limit as contingent upon that limit’s ability to prevent circumvention of the $1,000 base limit, describing the aggregate limit as “no more than a corollary” of the
