Scott Walker snuck by with only 53% of only because of near 100% turn out by conservatives. Those same conservatives will be nowhere near as excited for Mitt Romney who probably opposes half of Walkers measures.
I think Romney will fare better then McCain in Wisconsin, but not enough to carry it. Wisconsinite's still love their unions and Obama has a sizable chunk of support there.
This is a seven pt change in a month. The Disaster is finished. Conservatives are going to vote against him in droves. Forget the Cranks, Quakes and Perpetually POed. They wouldn’t vote for anyone around with ANY chance.
