As if it weren't already apparent, Scott Walker has badly overreached:
Given the distance between now and the 2012 elections, I don't know how much this matters. There's no guarantee that we'll still be talking about this in 20 months, and even still, a lot can change between now and the presidential election. Still, this is a huge change, and I'm sure other GOP governors will take note; attacking the most organized part of the Democratic base might not be a great idea if it ends up yielding a hyper-enthused Democratic electorate.
