As polls have closed in Wisconsin, the race remains too close to call. Early exit poll numbers in the recall suggest Republican Gov. Scott Walker and Democratic Milwaukee Mayor Tom Barrett are neck and neck, while data showed that labor turnout was markedly high. Nearly a third of voters in preliminary polls said they come from union households—an increase from two years ago when only 26 percent of voters represented unions. The high-labor turnout is a bonus for Barrett, since Walker has called for union restrictions. Preliminary numbers also showed that President Obama has 51 percent of voter support compared with Mitt Romney’s 45 percent.
