Supreme Court Strikes Down Law Barring Political Apparel at Polling Places.
'The Supreme Court on Thursday struck down a Minnesota law that prohibits voters from wearing T-shirts, hats and buttons expressing political views at polling places.
In a cautious 7-to-2 decision, the court acknowledged the value of decorum and solemn deliberation as voters prepare to cast their ballots. But Chief Justice John G. Roberts Jr. wrote that Minnesotas law was not capable of reasoned application.
Minnesotas law, similar to ones in about nine other states, is quite broad. It says that a political badge, political button or other political insignia may not be worn at or about a polling place on primary or Election Day.
As enforced by election officials, the law bans even general political messages on apparel, like support for gun rights or labor unions.'>>>
