Steuben's rural and small-city mix — anchored by Corning and Bath — has shifted steadily rightward over the past decade, with the 2024 presidential margin reaching its widest point in recent memory at R+31.7.
The Democratic margin in Steuben County peaked at twenty-one points in 1964. By 1968 the county had flipped, voting Republican for the first time in many years. The 2024 margin was thirty-two points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Steuben County's median household income of $65,887 sits well below state and national norms, and 14% 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 Licking County and Wayne County.
