In sum, we conclude that the district court—given the material issues of fact that exist—erred in holding that the State’s interest in preventing corruption or the appearance of corruption was insufficient as a matter of law to justify the ban on PAC-to-PAC transfers. Whether the anti-corruption interest is sufficient in light of the evidence in the record in this case, and whether the transfer ban is a closely drawn means of furthering that interest, given ADC’s dual account proposal, are mixed questions of law and fact that should be explored in the first instance by the district court.
