PPP's poll of the Michigan gubernatorial race is a pretty clear indicator this one has moved out of play for the Democrats, Virg Bernero's best efforts notwithstanding. A look at all polling shows that over the month of August, after the primary, this gradually moved from a lead for Republican Rick Snyder in the mid-teens, up to the low 20s.
Not only is there the problem of Bernero being weighed down by Jennifer Granholm's unpopularity (Bernero's at 28/43), but as PPP's Tom Jensen points out, this is one GOP primary where they actually managed to shepherd through their most electable candidate (a Bernero/Mike Cox race would have been interesting, but we won't get to find out). Snyder has 43/28 faves, including an amazing 53/17 among independents. With this race probably having already landed on the wrong end of DGA triage decisions, we're moving this race to Likely Republican (from Lean Republican).
