The race for the open U.S. Senate seat in South Carolina has shifted dramatically from a projected Republican victory to a tight contest. Six months ago, the election was expected to be a routine win for the state's dominant Republican Party. However, the sudden death of incumbent Senator Lindsey Graham in July and the subsequent appointment of his sister, Darline Graham, to finish the term have introduced significant uncertainty into the political landscape.
Darline Graham, who was previously a political novice, was appointed by Republican Governor Henry McMaster to complete her brother's term. The siblings had a close relationship, with Lindsey Graham helping to raise Darline after their parents died early in their lives. While the appointment was widely supported, her decision to seek a full six-year term surprised many observers. The snap primary held just one month after Lindsey Graham's death featured several prominent figures in South Carolina politics.
President Donald Trump has been a vocal supporter of Darline Graham, campaigning for her in the state and visiting twice in the final weeks before the general election. Although the President had previous disagreements with Lindsey Graham, he viewed him as an ally during his second term, particularly regarding the war with Iran. However, this presidential backing may be having mixed results. It has alienated some independent voters and frustrated supporters of U.S. Representative Ralph Norman, who criticized the President's interference in a state-level decision. Both groups have expressed unease about Graham's inexperience and the potential for a political dynasty.
Graham's inexperience became a focal point during a primary debate when she was asked about U.S. national security interests in Taiwan and the South China Sea. She struggled to provide a clear answer and admitted that national security was not her specialty. In response, national Republican groups have sent additional financial resources to South Carolina to bolster her campaign, even as party members maintain confidence that they will retain the seat.
Democrat Annie Andrews, who won her primary before Lindsey Graham's death, has been campaigning for over a year. Her campaign has gained visibility from high-profile Democratic visits, including former Transportation Secretary Pete Buttigieg and Senator Mark Kelly from Arizona. These visits align with South Carolina's position as the first state on the 2028 Democratic presidential nominating calendar. Andrews has recently run a more independent campaign, focusing on economic issues and portraying Graham as part of a Washington establishment that prioritizes its own interests over those of local residents.
The two candidates met for their only debate last month, where they exchanged criticism regarding the economy, the war with Iran, and artificial intelligence. Much of the debate centered on their relative qualifications. Andrews, who previously challenged Representative Nancy Mace in 2022, has not held office or run a statewide campaign before. Graham defended her candidacy by noting that she kept her maiden name to honor her parents, calling the topic a tragic memory.
A poll conducted by The New York Times and Siena College in October indicated a close race. However, historical data suggests caution is warranted. In 2020, polls also showed a tight contest, yet Lindsey Graham won his final reelection by a ten-point margin in what was the state's most expensive election. Since 1998, when Fritz Hollings won his last term, Republicans have held both Senate seats in South Carolina. The state has only one Democrat in the U.S. House, Jim Clyburn.
The political environment in South Carolina is further shaped by straight-ticket voting, which allows voters to select all candidates from one party. While the race for the open governor's seat has not appeared as competitive as the Senate contest, the current dynamics suggest a potentially historic outcome. Libertarian and Constitution Party candidates are also included on the general election ballot, adding further complexity to the voting options.
