Mitt Romney’s South Carolina support is soaring, but he’s not the only one getting a boost. A new CNN/Time/ORC International poll finds Rick Santorum’s base in the Southeastern state is expanding as well. Romney’s support there has nearly doubled since the beginning of last month—the former Massachusetts governor has won over a total of 37 percent of likely Republican voters in South Carolina. Gingrich's numbers, on the other hand, have dipped 25 percentage points to 18 percent, just below Rick Santorum, pitting the two against each other for second place. Ron Paul has actually doubled his support in South Carolina since the last poll—from 6 percent to 12 percent.
