Minnesota has a law making it illegal for a voter at the polls to wear anything that has political associations. The Minnesota law is far harsher than the normal state laws that make it illegal to wear anything at the polls suggesting support or opposition to any person, party, or ballot measure that is on the ballot.

The lower federal courts have consistently upheld the Minnesota law. A group called Minnesota Voters Alliance is hoping the U.S. Supreme Court will hear its case against the law. In December 16, 2013, the U.S. Supreme Court refused a similar case, but it had procedural problems. The new case is Minnesota Majority v Mansky, 16-1435.
