Morgan County's rural Appalachian character has pushed its presidential margins steadily rightward over two decades; the 53-point Republican margin in 2024 places it among the most one-sided counties in the state.
The Democratic margin in Morgan County peaked at fourteen points in 1964. By 1968 the county had flipped, voting Republican for the first time in many years. The 2024 margin was fifty-three points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Morgan County's median household income of $59,351 sits well below state and national norms, and 13% of residents live below the federal poverty line. The shift here is part of a broader realignment of working-class places across the country. The county's voting pattern over the last decade is most similar to that of Muskingum County and Huron County.
