Ohio County anchors West Virginia's Northern Panhandle along the Ohio River, where Wheeling's working-class and retiree population has driven a sustained realignment away from its mid-century Democratic base over the past decade.
The Republican margin in Ohio County reached its widest at thirty-one points in 2016. The margin in 2024 was twenty-six points, in line with the county's deep historical pattern.
Ohio County's loyalty is rooted in its place. Median household income of $57,094, a 90% non-Hispanic-white share, and a population of 41,582 together describe a community whose political habits are deeply settled. The county's voting pattern over the last decade is most similar to that of Tucker County and Hopkins County.
