Democrat-leaning polling firm PPP released a new South Carolina poll just before tonight's New Hampshire GOP debate. Some of their findings:

Mitt Romney's taken a modest lead in South Carolina. He's at 30% there to 23% for Newt Gingrich and 19% for Rick Santorum. None of the other candidates hit double digits- Ron Paul at 9%, Rick Perry at 5%, Jon Huntsman at 4%, and Buddy Roemer at 1% round out the field.

... Gingrich may be in second place right now but the candidate who would have the best chance of beating Romney in South Carolina is Santorum. He edges out Romney as the candidate with the best favorability rating at 63/21.

... Finally it's important to note how truly up in the air the South Carolina race is. 45% of voters are either undecided or open to changing their minds in the next two weeks. And when we asked folks who they thought had run the strongest campaign in the state 49% said they weren't sure, speaking to the fact that the campaign there really hasn't started yet. Romney's in the lead for now but a Gingrich or more likely Santorum surge certainly seems within the realm of possibility.
