2 NATIONAL REPUBLICAN SENATORIAL COMMITTEE v. FEDERAL ELECTION COMM’N Opinion of the Court Election Comm’n, 518 U. S. 604, 613–616, 618 (1996) (Colorado I) (controlling opinion of Breyer, J.). But FECA still limits a political party’s coordinated expenditures. As the name implies, a political party’s coordinated expenditures are the party’s expenditures on, for example, advertisements produced or distributed in consultation with a candidate’s campaign. The primary current justification for those limits is to prevent circumvention—that is, to prevent a donor from circumventing the statutory limits on contributions to candidates by making a large contribution to a party that the party then uses to support a particular candidate. Some 25 years ago in a case known as Colorado II, this Court—over the dissent of JUSTICE THOMAS for four Justices—upheld FECA’s limits on political-party coordinated expenditures. See Federal Election Comm’n v. Colorado Republican Federal Campaign Comm., 533 U. S. 431 (2001). But recently, a group of candidates and political committees filed a new lawsuit and argued that Colorado II is no longer good law (or should be overruled). They point to: the significant changes in this Court’s First Amendment campaign finance jurisprudence since 2001; the enhancements in the other tools available to the Government to prevent circumvention of the contribution limits, especially earmarking and disclosure laws; and the diminished relative power of political parties as compared to outside groups over the last 25 years, which has undermined a key premise of Colorado II. See McCutcheon v. Federal Election Comm’n, 572 U. S. 185 (2014); Federal Election Comm’n v. Ted Cruz for Senate, 596 U. S. 289 (2022); see also SpeechNow.org v. Federal Election Comm’n, 599 F. 3d 686 (CADC 2010) (en banc). In light of the doctrinal and factual changes since 2001, the United States agrees with plaintiffs that Colorado II no longer retains vitality. So the Government does not defend the constitutionality of the political-party coordinated-
