KAREN NELSON MOORE, Circuit Judge. Three Kentucky Republican Party county executive committees challenge the Kentucky Registry of Election Finance’s prohibition on expending funds in support of a state constitutional amendment on the November general-election ballot. The district court denied the executive committees’ application for a preliminary injunction. The executive committees seek an injunction pending appeal of the preliminary-injunction decision. Because we conclude that the executive committees are likely to succeed on the merits of their First Amendment claim, we grant the injunction pending appeal and order expedited briefing on the appeal of the denial of the executive committees’ motion for preliminary injunction.
