CHARLESTON, S.C. (AP) — The death of Sen. Lindsey Graham, who was running for a fifth term when he passed away over the weekend, began a tumultuous new chapter in South Carolina politics during a year that has already been full of upheaval.As the conservative state’s senior senator and an influential ally of President Donald Trump, Graham was presumed to be on a glide path toward reelection.Now, Gov. Henry McMaster must choose a temporary replacement who can serve until January while the state also prepares a special primary so voters can choose a new Republican nominee for the general election. The rare open Senate seat has ignited a scramble among South Carolina’s most ambitious conservatives, who have been eager to climb the political ladder.Republicans just finished a sprawling and bruising contest to figure out their nominee for succeeding McMaster, who is wrapping up his second term. State Attorney General Alan Wilson won the nomination, overcoming a field that included Lt. Gov. Pamela Evette, Rep. Nancy Mace and Ralph Norman — all of whom are now eyeing Graham’s seat.

How will a special primary work?According to South Carolina law, a one-week filing period for a special primary election begins on the second Tuesday after the candidate’s death, or July 21.The special primary election would be held on the second Tuesday after that filing period closes, or Aug. 11. Any necessary runoff would follow two weeks after that, or Aug. 25.
