The Republican primary in South Carolina had record turnout, with bigger gains in voter participation than in Iowa and New Hampshire earlier this month.
The Jan. 21 South Carolina vote drew 602,000 Republicans, a 35 percent increase over 2008 participation, as former U.S. House Speaker Newt Gingrich defeated former Massachusetts governor Mitt Romney, the front-runner in national Republican polls. Gingrich received 40 percent of the vote compared with Romney’s 28 percent.
