South Carolina's solidly Republican electorate underpins the strong trader consensus favoring the GOP nominee in the 2026 Senate race. The state has backed Republican presidential candidates by double-digit margins in recent cycles, including a 17.9-point Trump victory in 2024, and has not elected a Democratic senator since 1998. Darline Graham, appointed to the seat following her brother Lindsey Graham's death after his June primary win, secured the Republican nomination by defeating Rep. Ralph Norman 52.5%-47.5% in the August 25 special primary runoff. She faces Democrat Annie Andrews, a pediatrician who won her party's nomination outright. Recent polls show Graham leading by 7-9 points in the general election matchup, consistent with the state's partisan fundamentals and limited Democratic path in a non-competitive environment. The November 3 contest occurs amid standard midterm dynamics, with no major late shifts reported that would narrow the gap.
