While Mitchell seems to lean a bit to the right, their Georgia poll for last year seems spot-on:
http://landmarkcommunications.net/landmarkrosetta-stone-releases-final-sunday-poll-of-georgia-voters-for-president-senate/So perhaps we're getting a consensus: Kid Rock is about 10 points behind Stabenow without having announced a campaign. Indeed, she's up by about how much she was up by in 2012 at this point in the election. (And, again,
he hasn't announced)
So Likely D at this point but there's room for potential. Trump approval here is 43-51.
