RACINE, WI (WTAQ) - Controversial rock star Ted Nugent will hold a rally for U.S. Senate candidate Tommy Thompson on Thursday in Racine County. The musical event will be held in Sturtevant, just 19 days before Thompson squares off against three other Republicans in a primary for the Senate seat to be given up by the retiring Herb Kohl. Nugent made waves in April in a speech to the National Rifle Association. He was called to meet with the Secret Service after he called President Obama’s administration as “evil” and “America-hating.” Nugent urged voters to quote, “chop their heads off in November.” Nugent endorsed Thompson in March, saying he favored the former governor’s pro-gun policies dating back to the mid-90’s. Thompson, Eric Hovde, Mark Neumann, and Jeff Fitzgerald are running the August 14th Senate primary – and the winner will go up against Democrat Tammy Baldwin in November.
