But Walker's lead shrinks among independent voters, among whom the incumbent governor holds just a three-point advantage. That's an encouraging sign for Barrett, who must make inroads among swing voters as well as rally his Democratic base.

"Walker only leads among self-described Independent voters by 47.6%-44.6%, and the underlying numbers seem fluid. Still, some of Walker’s detractors have been vocal about the fact that Walker was duly elected in 2010 and in most states would not be able to be challenged with a recall without greater cause," said We Ask America in a release accompanying the results.

Many are looking to the June 5 election as a proxy battle for Republican austerity efforts, and as a measure of union influence in 2012. Labor has poured substantial resources into Walker's defeat, while conservative political action committees have also proven aggressive in the state.

But Wisconsinites on both sides of the aisle already seem extraordinarily motivated by their unusual recall. Some 95 percent of those reached by We Ask America said they were planning to vote in next month's election.
