If a report by Lansing-based MIRSNews is accurate, there is something to the rumors about Congressman Fred Upton looking at a run for the U.S. Senate against incumbent Democrat Debbie Stabenow. MIRS is citing a source close to Upton as saying he’s “90% there” and is “very seriously looking” at challenging Stabenow. Upton has repeatedly told WSJM News he’s concentrating on the job at hand in the U.S. House. Another Republican source is telling MIRS that Upton’s moderate record won’t work with the more conservative GOP base in the state following the election of Donald Trump as President, even with Trump’s approval rating in the state at a very low level. Former Michigan Supreme Court Chief Justice Bob Young Jr. and John James are the current Republican field for the Senate after Lena Epstein withdrew to run for the U.S. House yesterday.
