An up and coming Senate candidate in Michigan is getting some big-time support. Rockstar Kid Rock will campaign for John James at his upcoming rally.

According to The Daily Caller:

Kid Rock will rally with U.S. Army combat veteran John James, a Republican candidate for U.S. Senate in Michigan, The Daily Caller News Foundation has learned.

The announcement comes after Rock, a Michigan native, contemplated a Senate bid for several months before announcing he would not run in October. Rock later signaled early support for James when he invited him to sit court-side at a Detroit Pistons game in January.

“Kid Rock’s appearance on stage with John James would be a game changer if he formally endorses,” Matt Frendewey, a former spokesperson for the Michigan Republican Party, told TheDCNF. “If James gets a formal endorsement, it would be a massive boost for him and a devastating blow for his opponent Sandy Pensler, who recently came under attack for disparaging comments about the president.”

James’s “Rally to Take Back Michigan” will take place Tuesday in the Detroit suburb of Novi. As well as Rock, Rob O’Neill, the retired Navy SEAL who shot Osama Bin Laden, will also speak at the event. O’Neill endorsed James in late 2017.

James is running in the primary for the chance to take on Sen. Debbie Stabenow in November.
