Two new polls in South Carolina — both conducted after Monday’s presidential debate — show a very tight Republican primary race.

American Research Group: Newt Gingrich 33%, Mitt Romney 32%, Ron Paul 19%, Rick Santorum 9%, Rick Perry 4%.

InsiderAdvantage: Newt Gingrich 32%, Mitt Romney 29%, Ron Paul 15%, Rick Santorum 11%, Rick Perry 3%.

Caveat: Harry Enten makes a persuasive case that InsiderAdvantage has a pro-Gingrich bias to its results.
