Warren County's R+49.5 presidential margin in 2024 places it among Missouri's most lopsided exurban counties, reflecting the broad rural and small-town realignment that has reshaped the state's political map over the past decade.

The Republican margin in Warren County reached its widest at seventy-two points in 1920. The margin in 2024 was forty-nine points, in line with the county's deep historical pattern.

Warren County's loyalty is rooted in its place. Median household income of $81,209, a 90% non-Hispanic-white share, and a population of 37,177 together describe a community whose political habits are deeply settled. The county's voting pattern over the last decade is most similar to that of Franklin County and Morgan County.
