I'm interested to see the crosstabs, but if I had to guess, Trump has recovered in the WOW region. Even then, I still think a candidate who's favorables are 28/63 just simply can't win the state. There's not enough Obama/Walker voters to get him over the top.
Most of the WOW county R's will come around. They don't like Trump but they HATE Hillary, and she's a Dem so their hatred of the left will overcome most of their dislike of Trump in the end, but I imagine he'll get a much lower share of that vote.
Yeah... they could be coming home... but the propensity to vote might have been so low last time around that it looked competitive in WOW. The last Marquette poll was in the field at the height of the bounce/Khan fiasco... I imagine a lot of GOPers were abstaining.
