Wabash County, tucked into southeastern Illinois along the Indiana border, has delivered lopsided Republican presidential margins for over a decade, reflecting a broader rural realignment across the region's small agricultural communities.
The Democratic margin in Wabash County peaked at twenty-nine points in 1932. By 1968 the county had flipped, voting Republican for the first time in many years. The 2024 margin was fifty-four points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Wabash County's median household income of $57,086 sits well below state and national norms, and 17% 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 Richland County and De Witt County.
