Via Breitbart TV. Great news, guys: It only took 22 debates for someone to launch a full-bore attack on Romney’s biggest vulnerability.

Santorum came to play tonight, but if PPP’s brand new poll of South Carolina is correct, it’s too late. Newt still leads by six:

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)…

Santorum has the voters most likely to abandon him for one of the more viable contenders in the final 36 hours, with 32% of them saying they could end up voting for someone else. Gingrich is the second choice of 45% of Santorum voters open to changing their minds, compared to 22% for Romney.

Santorum didn’t do well enough tonight to win South Carolina, but did he do well enough to keep some of those would-be Newt voters from defecting? Two clips for you here, one of his RomneyCare answer and the other, via BuzzFeed, of him going hard after his friend and would-be “nonaggression pact” partner Newt. Exit question: Did Newt actually praise John King after the debate? What was all that screeching at the beginning about, then?
