Jefferson County, a former steel-industry stronghold along the Pennsylvania border, has shifted decisively over the past two decades — its 2024 presidential margin of R+43.9 reflects a working-class electorate that moved away from its historically Democratic roots.

The 2012 election was the turning point, when the Republican candidate carried the county by five points. The 2024 margin was forty-four points, in line with the county's new direction.

The demographics suggest why. A population of 64,518, a 89% non-Hispanic-white share, and a median household income of $59,055 situate the county in the broader realignment patterns of recent cycles. The county's voting pattern over the last decade is most similar to that of Belmont County and Pine County.
