Republican candidates gathered in Charleston, South Carolina Thursday night for their final debate before Saturday’s primary. The debate capped a busy day that saw the departure of Texas Governor Rick Perry, Rick Santorum’s defeat of Mitt Romney in the Iowa caucus recount, and new details of Newt Gingrich’s infidelities during his second marriage. In their remarks, Gingrich, Romney and Santorum each touted their right-wing credentials and took aim at President Obama.

Newt Gingrich: “It is imperative that we defeat Barack Obama. This is, I believe, the most dangerous president of our lifetime. And if he is re-elected after the disaster he has been, the level of radicalism of his second term will be truly frightening.”

Mitt Romney: “Our president said, I think in a very revealing way, that he wants to fundamentally transform America. He’s wrong. We need to restore the values that made America the hope of the earth.”

Rick Santorum: “South Carolina, you’ve been told in the past you’ve got to settle for a moderate because they can win. And you said, when the last time we had a situation like this in 1980, you said, 'No, we're going to take the strong conviction conservative.’”
