South Carolina's 1st congressional district features an open seat in 2026 after incumbent Nancy Mace opted to run for governor rather than seek re-election. The district carries a modest Republican tilt based on its partisan voting index and voting patterns in recent cycles, though it briefly flipped Democratic in 2018 before returning to GOP control. Republican nominee Jenny Costa Honeycutt, a Charleston County councilor, emerged from a competitive primary and runoff emphasizing border security and affordability, while Democrat Nancy Lacore won her party's nomination in the June runoff. Trader positioning reflects the seat's historical Republican performance and the structural advantages for the GOP in this coastal district ahead of the November general election, tempered by the potential for turnout shifts in a midterm environment.
