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.
With a 2024 presidential margin of R+43.6, District 105 sits firmly in South Carolina's heavily Republican interior, where low population density and rural demography produce some of the state's most consistent one-party results.
Across the recorded series it reached a Democratic high of 100.0 points in 1904 and a Republican high of 57.6 points in 1972. Between 2020 and 2024 the district moved 5.5 points toward the Republican candidate; the 2024 margin was 43.6 points.
A population of 40,569, a 73% non-Hispanic-white share, and a median household income of $62,485 describe the district. The district's voting pattern over the last decade is most similar to that of State House District 58 and State House District 155.
