Former President Bill Clinton has decided to go to Wisconsin to campaign against Scott Walker in the final days of the battle over whether to recall the Wisconsin Governor, a move that could give a boost to the anti-Walker forces in a campaign that will depend heavily on who turns out to vote, a source familiar with Clinton’s plans confirms to me.

As late as yesterday afternoon, it was still not certain whether Clinton would go to Wisconsin. DNC chair Debbie Wasserman Schultz, in a meeting with Democrats, seemed to suggest that he was trying to determine whether he would go. But neither the DNC nor Clinton’s camp would confirm whether it was going to happen, and Democrats cautioned that Clinton had not made up his mind.

But now he will go to Wisconsin, the source confirms.

Democrats badly want Clinton to campaign in Wisconsin for Tom Barrett, and had lobbied him heavily for weeks. But Clinton remaind undecided until today.

Public polls have shown Walker leading Barrett, but internal Dem polls have shown a dead heat. And even some neutral Wisconsin observers think that polling of this race may not be predictive, because turnout will likely be highly unpredictable in a mid-year gubernatorial recall election. What’s more, this election is expected to register far higher turnout than in the 2010 election that installed Walker in power in the first place, making it still harder to predict the outcome.

Labor and Dems are widely believed to have a superior ground game to that of Walker, though it’s still unclear whether it will be enough to compensate for Walker’s seeming lead in the polls. A Clinton visit, Dems hope, will galvanize base turnout (the black vote in Milwaukee, for example) just enough to put Barrett over the top.

More details to come.


UPDATE: Clinton is set to go to Wisconsin tomorrow, according to a second source. More Soon.
