South Carolina Political History & Voting Patterns
Solid D through 1960s; solid R since Strom Thurmond-era realignment. A complete guide to how South Carolina has voted in presidential elections, which coalitions have driven results, and how the state has shifted over time.
Historical Overview
South Carolina’s political history is bookended by Strom Thurmond, who began as a Democrat, ran the Dixiecrat presidential campaign in 1948, and ended his career as a Republican senator who died in office in 2003 at age 100. The state hosts the first-in-the-South presidential primary, giving it disproportionate 2024 influence. Nikki Haley’s governorship (2011-2017) and UN ambassadorship were South Carolina’s national political stories. Jim Clyburn’s enduring House Whip influence, particularly his pivotal 2020 endorsement of Biden before South Carolina’s primary, gives Democrats outsized national impact from a deeply red state.
