The remaining GOP candidates -- Mitt Romney, Newt Gingrich, Ron Paul and Rick Santorum -- are vying for the state's 25 delegates.
The Republican National Committee penalized the state for moving up its primary date, which violated party rules. So, along with four other states, South Carolina lost half its delegates to the August nominating convention.
The winner of Saturday's primary will receive 11 delegates, while the winner of each of the state's seven congressional districts will receive two delegates per district.
A candidate needs a total of 1,144 delegates to win the Republican nomination.
According to the latest polls, Gingrich has surged in recent days, edging Romney, the current frontrunner in the GOP race, by a roughly 10-point margin, with 26.8 percent of the vote. Paul and Santorum trail in third and fourth place, respectively.
In 2008, Romney came in fourth place in South Carolina, with only 15 percent of the vote.
