Cite as: 572 U. S. ____ (2014) 21 Opinion of ROBERTS, C. J. limits remain the primary means of regulating campaign contributions—the obvious explanation for why the aggregate limits received a scant few sentences of attention in Buckley.7 B “When the Government restricts speech, the Government bears the burden of proving the constitutionality of its actions.” United States v. Playboy Entertainment Group, Inc., 529 U. S., at 816. Here, the Government seeks to carry that burden by arguing that the aggregate limits further the permissible objective of preventing quid pro quo corruption. The difficulty is that once the aggregate limits kick in, they ban all contributions of any amount. But Congress’s selection of a $5,200 base limit indicates its belief that contributions of that amount or less do not create a cognizable risk of corruption. If there is no corruption concern in giving nine candidates up to $5,200 each, it is difficult to understand how a tenth candidate can be regarded as corruptible if given $1,801, and all others cor—————— at 31–38 (appendix A to opinion of BREYER, J.) (excerpts from McConnell record discussing unregulated “soft money”). Our holding about the constitutionality of the aggregate limits clearly does not overrule McConnell’s holding about “soft money.” 7 It would be especially odd to regard aggregate limits as essential to enforce base limits when state campaign finance schemes typically include base limits but not aggregate limits. Just eight of the 38 States that have imposed base limits on contributions from individuals to candidates have also imposed aggregate limits (excluding restrictions on a specific subset of donors). See Conn. Gen. Stat. §9–611(c) (2013); Me. Rev. Stat. Ann., Tit. 21–A, §1015(3) (Supp. 2013); Md. Elec. Law Code Ann. §13–226(b) (Lexis Supp. 2013); Mass. Gen. Laws, ch. 55, §7A(a)(5) (West 2012); N. Y. Elec. Law Ann. §14–114(8) (West Supp. 2013); R. I. Gen. Laws §17–25–10.1(a)(1) (Lexis 2013); Wis. Stat. §11.26(4) (2007–2008); Wyo. Stat. Ann. §22–25–102(c)(ii) (2013). The Government presents no evidence concerning the circumvention of base limits from the 30 States with base limits but no aggregate limits.
