Each row is a county-allocated estimate of U.S. House votes for this district — county returns apportioned onto its boundary, not precinct-counted. “Vote lead” is the estimated local lead here, not necessarily the winner of the full contest.
District 85 sits among South Carolina's narrower legislative battlegrounds, where a 4.9-point Democratic presidential lean signals a persuadable electorate rather than a locked partisan base.
Across the recorded series it reached a Democratic high of 99.4 points in 1940 and a Republican high of 65.0 points in 1972. Between 2020 and 2024 the district moved 2.5 points toward the Republican candidate; the 2024 margin was 22.1 points.
A population of 40,468, a 73% non-Hispanic-white share, and a median household income of $88,440 describe the district. The district's voting pattern over the last decade is most similar to that of State House District 74 and State House District 69.
The state-house districts 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.
