Washington — South Carolina voters are heading to the polls Saturday for the state’s Republican presidential primary, the fourth primary contest of the 2024 campaign. Read on to find out when polls open and what time they’ll close. 

The state’s former governor, Nikki Haley, is the last major Republican running against former President Donald Trump for the nomination. He has won all of the GOP contests so far: Iowa, New Hampshire, Nevada and the U.S. Virgin Islands, and he was leading polls in Haley’s home state through primary day. 

South Carolina is an open primary state, so Republicans or Democrats may vote in the GOP primary, as long as they didn’t vote in the Democratic primary earlier this month.
