The South Carolina Senate race, long held by Republicans, has become unexpectedly competitive in the 2026 midterm elections. Darline Graham, who was appointed to the seat following the death of her brother, Senator Lindsey Graham, in July, now faces a strong challenge from Democrat Annie Andrews. Updated ratings from Sabato’s Crystal Ball have shifted the race from Safe to Likely Republican, signaling a closer contest as Democrats capitalize on President Donald Trump’s declining approval ratings.
Shift in Race Ratings Reflects Growing Competitiveness
Sabato’s Crystal Ball moved the South Carolina Senate race into the battleground category on Tuesday, citing polling that shows Darline Graham holding only a narrow lead over Annie Andrews. The state, which backed President Trump by 18 points in the 2024 election, is not usually seen as competitive. However, recent polls, including those from conservative pollsters, reveal a close contest. Both President Trump and Senate Majority Leader John Thune are expected to campaign in South Carolina to support Graham.
Candidates and Campaign Dynamics
Darline Graham was appointed by Republican Governor Henry McMaster following the death of her brother, Lindsey Graham, who served as senator for more than 20 years and was up for reelection this year. Darline Graham won a quick primary with Trump’s endorsement and was sworn in on July 14, 2026. Her opponent, Annie Andrews, a pediatrician and 2022 congressional candidate, has gained attention by positioning herself as a credible candidate capable of appealing to independents and some Republicans.
Andrews spoke at the Spratt Issues Conference on August 22, 2026, in Florence, South Carolina, emphasizing her commitment to earn votes across the state. She criticized Graham for acting as though the seat is hers to inherit, stating, “I think it belongs to the people of South Carolina, and I’m going to keep earning their votes in every corner of this state between now and November.” Andrews also recently broke from her party on transgender athlete policies, stating she does not support biological men competing in women’s sports or gender surgery for minors.
Political Environment and Election Outlook
The Senate Leadership Fund, aligned with GOP leadership, has invested $5 million in South Carolina to bolster Graham’s campaign as the election nears. Despite this, experts note the political environment favors Democrats more than usual due to economic concerns and dissatisfaction with the current administration. Political science professor Justin Vaughn of Coastal Carolina University indicated that Andrews’ path to victory requires strong Democratic turnout, winning independents, and some Republicans either crossing over or abstaining from voting. He cautioned, however, that South Carolina’s strong Republican lean still gives Graham an edge.
Polling data from InsiderAdvantage shows Graham leading by just one point with 46 percent support, underscoring the race’s tight margins. Both Sabato’s Crystal Ball and The Cook Political Report currently classify the race as Likely Republican, reflecting the uncertainty in this traditionally red seat.
Impact of National Politics on the Race
Democrats see an opportunity to compete in more conservative states this midterm cycle, leveraging President Trump’s record-low approval ratings amid voter frustration over the economy, inflation, and foreign policy issues such as the Iran war. Historically, the president’s party tends to lose seats during midterms, and Democrats aim to make this election a referendum on Trump’s policies. South Carolina, while not a primary target in past cycles, has emerged as a notable battleground due to these shifting dynamics.
The upcoming weeks are critical as Trump is expected to campaign in the state, seeking to solidify Graham’s support. Meanwhile, Democrats continue to push Andrews’ message of change and responsiveness to voter concerns, hoping to capitalize on the evolving political landscape.
As the November election approaches, South Carolina voters will decide whether to maintain the long-standing Republican hold on this Senate seat or embrace a new direction with Annie Andrews.
