South Carolina Republican primary: when to expect results and what they can tell us

Former South Carolina governor and UN ambassador Nikki Haley makes a stand on home turf against former boss Donald Trump

South Carolina Republicans will pick their candidate for president Saturday in the first in the South" primary. Former president Donald Trump faces his former UN ambassador, Nikki Haley, on her home turf in a state that makes or breaks Republican candidacies. Haley has outlasted Trump's other primary competitors and will make a stand in the state she served as governor for six years, but polling suggests she's likely to be blown out.

South Carolina's Democrats voted two weeks ago, giving president Joe Biden 96% of their votes in what increasingly appears to be a coronation parade to the nomination.
