National Republican Senatorial Committee v. Federal Election Comm’n · ¶33

But the modern congressional limits on political-party coordinated expenditures restrict that coordination and the party’s speech. The limits impair the party’s traditional forms of communication such as advertisements; preclude parties from amplifying the voice of their adherents; impose additional monetary costs and burdens on political parties; and inflict a “stifling effect on the ability of the party to do what it exists to do.” Colorado I, 518 U. S., at 630 (opinion of Kennedy, J.); see also Colorado II, 533 U. S., at 469–471 (THOMAS, J., dissenting).
