Byron York hits the trail with Rudy Giuliani in South Carolina, and notes a changing aspect of the state--northern retirees (largely from New York and New Jersey) moving to the Palmetto state. They tend to be more economically conservative than socially conservative, and Giuliani is courting them heavily. New York transplants are no doubt one source of Giuliani's strength in Florida, but York's column sheds some interesting light on how immigration from the north could help him in South Carolina as well.
