Crawford County's R+53 margin in 2024 places it among Ohio's most heavily Republican jurisdictions, reflecting the broader consolidation of rural, small-manufacturing communities away from competitive voting patterns over the past decade.
The Democratic margin in Crawford County peaked at forty-one points in 1912. 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. Crawford County's median household income of $58,044 sits well below state and national norms, and 12% 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 Morrow County and Champaign County.
