Senate Runoff voting will determine the Republican nominee in South Carolina’s special election to replace Lindsey Graham. Darline Graham and Rep. Ralph Norman finished ahead of their Republican opponents but failed to secure majority support. Therefore, the two candidates will meet again in a runoff election scheduled for two weeks later. Rep. Russell Fry and former Gov. Mark Sanford finished behind the leading candidates and will not advance.
The primary followed the unexpected death of Sen. Lindsey Graham, who died at age 71. Gov. Henry McMaster appointed Darline Graham, Lindsey Graham’s younger sister, to temporarily fill his Senate seat. She will serve until voters choose someone to complete the remainder of the term. Consequently, Tuesday’s contest carried significant importance for Republicans across the state.
President Donald Trump endorsed Darline Graham before the primary and strongly promoted her candidacy. Graham emphasized that endorsement during her primary night remarks while thanking Trump for his support. She also pledged to continue supporting the president’s political agenda if elected. However, the results showed that Trump’s endorsement did not produce an outright primary victory.
Norman also built his campaign around strong support for Trump and his administration’s priorities. The Republican congressman previously sought the GOP nomination for governor earlier this year. Although that campaign ended unsuccessfully, Norman quickly shifted his attention toward the open Senate opportunity. His advancement now gives him another chance to compete for statewide office.
Meanwhile, Fry also promoted his alignment with Trump during his Senate campaign. The two-term congressman attracted support from voters but failed to secure enough votes for the runoff. Sanford likewise remained in contention throughout the primary while emphasizing his longstanding fiscal conservatism. He frequently focused on federal spending and the nation’s growing debt during his campaign.
The crowded Republican field made a majority victory difficult for any candidate. Because no contender reached the required threshold, South Carolina election rules triggered another contest. The upcoming Senate Runoff will now narrow the Republican field to Graham and Norman. Their campaigns will likely intensify efforts to attract supporters from eliminated candidates.
The contest also provides another test of Trump’s influence inside the Republican Party. His endorsement helped Graham emerge as a top contender, yet she still must win another election. Earlier this year, Trump experienced a similar setback during South Carolina’s gubernatorial contest. He initially backed Lt. Gov. Pamela Evette, who later lost the Republican runoff to Attorney General Alan Wilson.
Republicans will therefore watch the Senate Runoff closely as both candidates compete for broader support. The winner will become the Republican nominee for the special general election. Democratic nominee Annie Andrews, a pediatrician, already awaits the eventual Republican opponent. Given South Carolina’s Republican leanings, the runoff winner enters the general election as the expected favorite.
However, Tuesday’s results demonstrate that Republican voters still have meaningful choices despite Trump’s endorsement. The final outcome will depend on turnout, campaign organization, and how eliminated candidates’ supporters respond. For now, Graham and Norman remain focused on securing the nomination before the general election.
