Gasconade County's 2024 presidential margin of R+60.2 reflects a broader Ozark-fringe shift toward dominant Republican performance, with its small, majority-white rural population showing little sign of competitive volatility in recent cycles.
The Republican margin in Gasconade County reached its widest at eighty-one points in 1920. The margin in 2024 was sixty points, in line with the county's deep historical pattern.
Gasconade County's loyalty is rooted in its place. Median household income of $64,232, a 95% non-Hispanic-white share, and a population of 14,746 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 Livingston County and Warren County.
