Three hours before the polls closed, exit polls indicated a tight race in the Wisconsin recall election, with Governor Scott Walker holding a small advantage.

39% - STRONGLY APPROVE

11% - SOMEWHAT APPROVE

5% - SOMEWHAT DISAPPROVE

43% - STRONGLY DISAPPROVE

Walker leading 50% to 48% on this measure - too close to feel much comfort. Strong approval of Walker's handling of the economy is a good sign for Walker, but an increase in union participation would favor Barrett.

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.
