Sebastian County's population clusters around Fort Smith, the state's second-largest city, yet it still posts presidential margins exceeding 37 points for Republicans — suggesting urban concentration alone doesn't moderate partisan lean in this corner of the Ozark Plateau.
Across the recorded series it reached a Democratic high of 59.1 points in 1936 and a Republican high of 62.6 points in 1972. Between 2020 and 2024 the county moved 2.1 points toward the Republican candidate; the 2024 margin was 37.5 points.
A population of 128,900, a 66% non-Hispanic-white share, and a median household income of $57,790 describe the county. The county's voting pattern over the last decade is most similar to that of Crawford County and Toombs County.
