The polls have closed in Wisconsin's recall vote for GOP Gov. Scott Walker, with the votes still too close to call.
Fox News exit polls show the race is extremely tight, so it is too early to say whether Walker will become the first governor in U.S. history to survive a recall election.
Voter turnout was reportedly heavy, as expected, in the race between Walker and Democratic challenger Tom Barrett, the Milwaukee mayor he faced in 2010.
The recall effort started about 18 months after the first-term governor eliminated collectively bargain agreements for most state employees, in an effort to cut Wisconsin's multi-billion dollar budget shortfall.
Democrats and unions argued that Walker had gone too far, then helped organize massive statehouse protests and gather 900,000 signatures for the recall vote. The effort began shortly after the state legislature agreed last year to Walker’s proposal, which also requires most public state workers to pay more for health insurance and pension benefits.
Roughly $63 million was spent on the race, with much of Walker’s money coming from outside of the state.
