Christian County, anchored by the small city of Taylorville, has shifted decisively toward Republican presidential candidates over the past two decades, with 2024 margins exceeding 46 points in a county once competitive enough to elect Democrats statewide.
The Democratic margin in Christian County peaked at thirty-two points in 1964. By 2000 the county had flipped, voting Republican for the first time in many years. The 2024 margin was forty-seven points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Christian County's median household income of $62,611 sits well below state and national norms, and 10% 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 Saline County and McLean County.
