Romney went from almost certainly sweeping the first three to being tied at one a piece with Gingrich and Santorum. He is still the front runner, but a lock he is not.
"Newt Gingrich resurrected his campaign Saturday with a convincing victory in the South Carolina Republican presidential primary, leveraging strong debate performances and a handful of wrong turns by Mitt Romney to surge past the former frontrunner and reset the race now headed to Florida.
After claiming his first primary win, the former House speaker rallied supporters on the road to the next contest on Jan. 31. Gingrich, looking to convey the image of a general election candidate, focused his victory speech almost entirely on President Obama, unloading some of his toughest criticism to date on the White House incumbent.
Gingrich locked up a decisive victory in the state. With 100 percent of precincts reporting, Gingrich pulled in 41 percent of the vote, to Romney's 27 percent. Rick Santorum finished in third with 17 percent, followed by Ron Paul with 13 percent. Herman Cain, who dropped out before the first contest, garnered 1 percent.
The leader board virtually ensures a drawn-out Republican race, a turnaround from just a week ago when Romney seemed poised to clinch the nomination in short order. While South Carolina has predicted the presidential candidate every year since 1980, the candidate in previous victories had won either Iowa or New Hampshire."
