New polling data shows almost half of the Republicans in Michigan haven’t yet made up their mind in a GOP primary for the U.S. Senate. They’ve still got plenty of time ahead of the primary next year, but polling by Target Insyght puts Congressman Fred Upton second in the race. Political newcomer John James, who is calling himself a “conservative outsider” has the lead with 24%, followed by Upton at 19% and former Michigan Supreme Court Chief Justice Bob Young at 7%. “Other” candidates are supported by 5% of those polled, while 45% are still undecided. James has been releasing daily videos to speak directly to voters, while Upton has not made a decision on whether to run for the U.S. Senate or seek re-election to the U.S. House. Democratic incumbent Debbie Stabenow is seeking re-election to the Senate. Singer Kid Rock said recently he was not serious when he teased a possible run against Stabenow as a Republican, and admitted that was a promotional stunt for his new album.
