CHARLESTON, S.C. (AP) — Donald Trump has won South Carolina’s Republican primary, beating his last major rival, former U.N. Ambassador Nikki Haley, in her home state. Trump has now swept every contest that counted for Republican delegates, adding to previous wins in Iowa, New Hampshire, Nevada and the U.S. Virgin Islands. A 2020 general election rematch against President Joe Biden is all but inevitable. The former president’s latest victory Tuesday will increase pressure on Haley, who was South Carolina governor from 2011 to 2017, to leave the primary race. But Haley has raised copious amounts of campaign funds and vowed to stay in the race despite increasing questions about where she might win any upcoming contests.
