The main districts to watch are the last one in Dane, the 12 in Milwaukee, and the 21 in Eau Claire. (and any others the AP might have screwed up that we don't know about yet)

I think Marathon is alll in and AP is just screwing the pooch again. They have cast 61% of the voted they cast in the 2010 Walker election which is pretty much what Milwaukee, Waukesha and Racine cast. Dane otoh has cast 82% of the votes they cast in the last election.
