In its decision yesterday in Minnesota Voters Alliance v Mansky, the Supreme Court ruled that a Minnesota law banning political apparel at polls ran afoul of the First Amendment. The ruling was 7-2, a classic line-up in which the conservatives, Ginsburg, and Kagan joined in a strong free speech stand while Sotomayor and Breyer were more deferential toward speech restrictions. Cato had urged in a brief that the law be overturned.
For the majority, Chief Justice Roberts wrote that while the aim of Minnesota’s law was constitutionally acceptable (keeping peaceful order and preventing electioneering at the polls) the details of its drafting were not. “A rule whose fair enforcement requires an election judge to maintain a mental index of the platforms and positions of every candidate and party on the ballot is not reasonable.” So the proposition is not that states can’t regulate the wearing of campaign paraphernalia into the polling place, but that Minnesota needs to come up with rules that are more readily enforced in an even-handed way.
