Newt Gingrich surged to victory in South Carolina in part thanks to billionaire casino owner Sheldon Adelson, who gave $5 million to a pro-Gingrich super PAC. Much of the money was used to buy airtime to attack Romney. Gingrich was also widely accused of employing the so-called “Southern strategy” to appeal to the prejudices of white voters in the South. Last week former President Jimmy Carter said there is a “subtlety of racism” to Gingrich’s comments about food stamps and welfare. House Assistant Minority Leader James Clyburn of South Carolina repeated a similar charge on Sunday.

Rep. James Clyburn: “He’s appealing to an element in his party that will see President Obama as different from all the other presidents that we have had.”
