Ohio's 15th stretches from the southwestern fringe of Franklin County into reliably Republican rural territory, producing a 16-point presidential margin in 2024 that reflects the broader realignment of working-class and small-town Ohio away from its historic swing-state identity.
Across the recorded series it reached a Republican high of 10.4 points in 2016. Between 2020 and 2024 the district moved 2.6 points toward the Republican candidate; the 2024 margin was 9.9 points.
A population of 786,636, a 75% non-Hispanic-white share, and a median household income of $76,704 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 12 and Congressional District 10.
The congressional 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.
