U.S. Supreme Court Justice Samuel Alito Jr. was on a roll Wednesday with a litany of hot-button, current events tests of what apparel a Minnesota law might prohibit a voter from wearing inside a polling place.

Alito’s hypotheticals dominated the questioning of Daniel Rogan, the state’s lawyer, in the U.S. Supreme Court arguments in Minnesota Voters Alliance v. Mansky. The Minnesota Voters Alliance and several individuals are challenging the constitutionality of a state law that bans wearing “political badges, political buttons or political insignia” in the polling place.
