Latest poll has Fred 24, Romney 20, Giuliani 15 (reported here in The State; I saw it in the Hotline). A friend of mine a while ago was predicting a Romney rise in South Carolina, arguing that the image of the state as a bastion of the type of voters who would automatically reject a Mormon is badly outdated. Looks like he was right.
UPDATE: It’s a Romney internal poll, so grain of salt…
