Henderson County's rural northwest Illinois landscape and dwindling population track closely with a decades-long shift toward lopsided Republican margins, hitting R+38.8 in 2024 despite the county casting fewer than 3,500 total votes.
The Republican margin in Henderson County reached its widest at fifty-six points in 1920. The margin in 2024 was thirty-nine points, in line with the county's deep historical pattern.
Henderson County's loyalty is rooted in its place. Median household income of $62,227, a 94% non-Hispanic-white share, and a population of 6,193 together describe a community whose political habits are deeply settled.
