Incumbent Republican Senator Lindsey Graham leads early general election polls against Democratic frontrunner Annie Andrews by mid-single digits, reflecting South Carolina's deep-red partisan lean and historical precedent where no U.S. senator from the state has lost re-election in over 80 years. Recent trader consensus at 75.5% for a Republican winner stems from Graham's institutional backing—including endorsements from President Trump, Governor Henry McMaster, and Senator Tim Scott—despite primary challenges ahead of the June 9 Republican primary. A March Pulse Opinion Research poll showed Graham at 41% among likely GOP voters, with challenger Mark Lynch at 21% and 22% undecided, potentially forcing a runoff, but his fundraising edge and incumbency solidify the party's strong path to victory.
