Newt Gingrich has won the South Carolina GOP Presidential primary, beating rival Mitt Romney, according to reports.

Three networks, The Washington Post, and a number of other news outlets have already called the race for the former speaker of the House of Representatives.

Though the polls have just closed in South Carolina and only about 1 percent of precincts are in, exit polls reveal that Gingrich appears to have the nomination locked up.

CBS News, NBC News and ABC News have all projected that Gingrich will be the winner, despite the fact that the polls closed at 7 p.m. and many precincts have not yet reported vote tallies.

Gingrich surged to the front in the Palmetto State over recent days, capitalizing on a scintillating South Carolina debate performance and harsh criticism of Romney's career at Bain Capital to make a last-minute appeal to the state's voters.
