While its very early yet, Republican Attorney General Bill Schuette is the current favorite for Governor, since Rick Snyder is term limited. Debbie Stabenow is up for re-election in 2018. Repubs think they might have a shot at this seat, particularly now that Kid Rock is no longer a candidate.
I'd love to see Dopey Debbie get sent home, but I won't bet the mortgage on it. The race for the House seats will be the usual circus.
