Jackson County's working-class river towns and agricultural hinterland have tracked a steady rightward shift over 15 years, with the 2024 presidential margin reaching R+32.5 — roughly double what it recorded in the early Obama era.
The county's recent history is a story of close margins. The Democratic margin reached twenty-six points in 1932; the Republican margin reached forty points in 1920. Most other elections have been decided by single-digit points.
Jackson County's demographics — a population of 19,390, a 95% non-Hispanic-white share, a median household income of $74,186 — situate the county close to national averages on several dimensions. The county's voting pattern over the last decade is most similar to that of Floyd County and Worth County.
