Seneca sits at the western tip of South Carolina's Upstate, where textile-era demographics and proximity to Clemson University create an electorate that trends heavily Republican but shows measurable ticket-splitting in local races.
Across the recorded series it reached a Democratic high of 99.2 points in 1932 and a Republican high of 58.2 points in 1972. Between 2020 and 2024 the metro moved 4.1 points toward the Republican candidate; the 2024 margin was 51.5 points.
A population of 80,469, a 83% non-Hispanic-white share, and a median household income of $62,388 describe the metro. The metro's voting pattern over the last decade is most similar to that of Sevierville, TN and Somerset, KY.
The metros whose fingerprint — 2000–2024 trajectory, demographics, ancestry, religion — sits closest to this one, and why.
Twin score (0–100) = weighted cosine between tier-standardized fingerprints: presidential margins 2000–2024 with 12-yr trend and elasticity, ACS income, age, education, population and race, top reported ancestries, and religious adherence — chips name the closest-shared dimensions and the widest gap.
