Thursday may have been one of the most eventful days of the Republican campaign so far, but the state of the race in South Carolina didn't change much. Newt Gingrich continues to lead Mitt Romney by 6 points, 35-29, with Ron Paul and Rick Santorum each tied for third at 15%.

Revelations from the Marianne Gingrich interview haven't taken a toll on Newt's image yet. For the first time in our South Carolina tracking this month his favorability is better than Romney's, with 53% of voters holding a positive opinion of him compared to 51% for his chief competitor.

Gingrich's lead with evangelicals held steady today at 40-22 over Romney. He's also doing well with Tea Party voters (46-21), registered Republicans (38-30), voters describing themselves as very conservative (41-21), men (39-27), and voters in the Upstate (36-25).

Romney is leading with non-evangelicals (39-30), independents (30-26), moderates (44-23), and women (32-31). The problem for him is that all of those groups are a minority within the South Carolina Republican electorate.

Newt also leads in the Rasmussen (33-31) and Insider Advantage (32-29) polls

Mitt leads in the Politico (37-30) and NBC/Marist (34-24) polls
