Bond County, anchored by the small city of Greenville, sits in southwestern Illinois farm country and has swung increasingly toward Republican presidential candidates over the past decade, posting a 44.7-point margin in 2024.
The Democratic margin in Bond County peaked at eleven points in 1964. By 2000 the county had flipped, voting Republican for the first time in many years. The 2024 margin was forty-five points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Bond County's median household income of $65,959 sits well below state and national norms, and 11% 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 Greene County and Switzerland County.
