WASHINGTON — The head of a major Super PAC aligned with Senate GOP leadership has encouraged performer Kid Rock to run for Senate against Democratic incumbent Debbie Stabenow of Michigan.

Steven Law in an interview Friday on C-SPAN’s “Newsmakers” program insisted he was quite serious, saying his group would “be actually very interested” in a Kid Rock candidacy.

The entertainer has made some moves to look at the race, including setting up a campaign website and creating what he said is a nonprofit group to promote voter registration. He posted a statement on his website on July 26 saying he would announce a decision about the race in six weeks or so.
