Another day, another South Carolina poll showing Mitt Romney with a double-digit lead in South Carolina. Yesterday it was Insider Advantage showing Romney up 32% to 21% over Newt Gingrich. Today it is Monmouth University showing a similar 33% to 22% lead.

According to data released by Monmouth, every demographic subgroup but one prefers Romney over Gingrich. Only those who identify themselves as “very conservative” choose Gingrich over Romney, and only by a 30% to 25% margin. Evangelicals, Tea Party supporters, men, women, young, and old all picked Romney over Gingrich, although his lead among evangelicals was only 3 points, 29% to 26%.
