WATCH Donald Trump Is Projected to Win the South Carolina GOP Primary

The South Carolina Republican primary appears to be a three-person race between Donald Trump, Ted Cruz and Marco Rubio, based on exit poll data. ABC News has not projected a winner yet.

Texas Sen. Ted Cruz won the Republican Iowa caucuses, the first contest of the 2016 presidential race, and Donald Trump won the New Hampshire Republican primary.

Since 1980, the Palmetto State has picked the eventual Republican nominee in every election cycle except in 2012, when Newt Gingrich beat out Mitt Romney in the primary.
