Democratic Onondaga County Elections Commissioner Dustin Czarny says, “You’re not allowed to do that within 100 feet of the polling place. There’s distance markers outside the doors and if you show up with that, elections inspectors are going to either ask you to either take off your buttons or even turn your shirt inside out because there is no electioneering allowed inside of a polling place and there never has been.”
