The Democrats shouldn't be leaving the state, but the Republicans have handled this whole situation badly. They got the majorities in Wisconsin, Indiana, and Ohio, and what did they do with it? They attempted to bulldoze the other side like thugs. In doing that, they started a war they could very well lose. They are already talking about recalling 7 GOP Senators in Wisconsin. This was the most ham-handed use of power I have ever seen. Not only that, but allowing themselves to be bankrolled by the infamous Koch Brothers? That was a huge mistake, as the opposition is now fired up like I haven't seen them in years, and they will now be able to get a lot of mileage out of their accusations of class warfare.
The Republicans are like bulls in a china shop. They might have some good points to make, and good things to do, but that is all being drowned out by a war they were itching to fight. Well, they've now got their war, and public opinion is now turning against them in a very bad way.
