Why is Wisconsin just "Dem lean"? Since Walker came into power, that state has moved significantly into the Pro-Obama column. His approvals in WI are among the highest in the nation by state. It is about as "Dem Solid" as they come.
That is not true by any means. Do you have any proof?
http://polltracker.talkingpointsmemo.com/contests/wi-approval-obamaSo I exaggerated that WI was "among the highest in the nation", but recent polls (scroll down on the page to see recent polls from PPP and the WI Research Institute) have him in the 52-53 range with disapproval in the 42-44 range. Since Walker came into power and began royally pissing off every Wisconsinite who pays attention, Democrats approvals in general have soared. It's been like that in some states that are now under tea party run state governments.
I'll admit that a lot can happen between now and Nov. 2012, but at this point WI seems to be solid Dem.
