Rasmussen Reports polled South Carolina yesterday and found:

What a difference a caucus makes. Rick Santorum who two months ago had one percent (1%) support among likely South Carolina Republican Primary voters now is running a close second there with 24% of the vote.

The latest Rasmussen Reports telephone survey in the Palmetto State finds former Massachusetts Governor Mitt Romney still in the lead, earning 27% support from likely GOP Primary Voters, up from 23% in early November. Former House Speaker Newt Gingrich is in third with 18% of the vote, followed by Texas Congressman Ron Paul at 11%.

... In the first Rasmussen Reports survey of the South Carolina Republican Primary race in November, Georgia businessman Herman Cain came in first with 33% support, followed by Romney and Gingrich. Cain has since dropped out of the race.
