Ted Nugent plays his guitar during an interview before a concert at the House of Blues at the Mandalay Bay Resort in Las Vegas, Nevada in this file image from August 11, 2007. Republican candidate Mitt Romney's campaign called for civility on Tuesday after aging rock star Nugent made an apparent threat against President Barack Obama before an audience of U.S. gun lobbyists. Nugent told the National Rifle Association convention in St. Louis last week that "If Barack Obama becomes the president in November again, I will either be dead or in jail by this time next year."
