Cite as: 558 U. S. ____ (2010) 41 Opinion of the Court With regard to large direct contributions, Buckley rea soned that they could be given “to secure a political quid pro quo,” id., at 26, and that “the scope of such pernicious practices can never be reliably ascertained,” id., at 27. The practices Buckley noted would be covered by bribery laws, see, e.g., 18 U. S. C. §201, if a quid pro quo arrange ment were proved. See Buckley, supra, at 27, and n. 28 (citing Buckley v. Valeo, 519 F. 2d 821, 839–840, and nn. 36–38 (CADC 1975) (en banc) (per curiam)). The Court, in consequence, has noted that restrictions on direct contri butions are preventative, because few if any contributions to candidates will involve quid pro quo arrangements. MCFL, 479 U. S., at 260; NCPAC, 470 U. S., at 500; Fed eral Election Comm’n v. National Right to Work Comm., 459 U. S. 197, 210 (1982) (NRWC). The Buckley Court, nevertheless, sustained limits on direct contributions in order to ensure against the reality or appearance of cor ruption. That case did not extend this rationale to inde pendent expenditures, and the Court does not do so here. “The absence of prearrangement and coordination of an expenditure with the candidate or his agent not only undermines the value of the expenditure to the candidate, but also alleviates the danger that expenditures will be given as a quid pro quo for improper commitments from the candidate.” Buckley, 424 U. S., at 47; see ibid. (inde pendent expenditures have a “substantially diminished potential for abuse”). Limits on independent expendi tures, such as §441b, have a chilling effect extending well beyond the Government’s interest in preventing quid pro quo corruption. The anticorruption interest is not suffi cient to displace the speech here in question. Indeed, 26 States do not restrict independent expenditures by for profit corporations. The Government does not claim that these expenditures have corrupted the political process in those States.
