National Republican Senatorial Committee v. Federal Election Comm’n · ¶76

The political-party coordinated-expenditure limits at issue here would operate as a fourth line of defense. Such a “prophylaxis-upon-prophylaxis approach requires that we be particularly diligent in scrutinizing the law’s fit.” Ibid. (quotation marks omitted). But the fourth prophylaxis imposes a severe and direct restriction on free speech and infringes fundamental First Amendment values. Otherwise stated, the restriction on political-party coordinated expenditures is “disproportionate” and is not “necessary” and “narrowly tailored” to the Government’s interest in preventing circumvention of the base contribution limits. Id., at 199, 218, 220 (quotation marks omitted); Cruz, 596 U. S., at 306.
