Won't matter. The MSM will hint around, make up stuff wholesale with the disclaimer "unnamed sources say", etc. until it takes it's toll on Walker's campaign.
What all this really means is that the dems are scared to death of him.
He's already proved he can take them on and is willing to go around him. They tried to do it already, even on a national level during his election, his recall election and reelection. He won't let them get away with it. That's part of the reason for his success. It's like that stupid evolution question. He just told them he wasn't there to discuss it and went on. They tried to make hay about it but it didn't work. He's smart enough to not fall into their trap. Now they're on to his lack of college education. Rather than be a drawback, I think this will actually be an asset. The entire country is damn tired of elites who want to rule instead of govern. He's one of us and that could be his biggest asset. He's nowhere near an inside the beltway guy. No one they could run on the left, even the fake Indian and that socialist Bernie Sanders can touch that. Hell, with the exception of Rick Perry, no one on our side can either. I don't think a Senator or Representative can win. That's where 0bama came from and he can't govern. That body will be suspect for a while. Though there are plenty that would make good VP candidates.
