Marion County anchors Missouri's northeastern corner along the Mississippi, where a shrinking small-city population and deep agricultural roots have pushed presidential margins from competitive to lopsided since the early 2000s.
Across the recorded series it reached a Democratic high of 42.5 points in 1932 and a Republican high of 52.9 points in 2024. Between 2020 and 2024 the county moved 2.7 points toward the Republican candidate; the 2024 margin was 52.9 points.
A population of 28,457, a 89% non-Hispanic-white share, and a median household income of $62,903 describe the county. The county's voting pattern over the last decade is most similar to that of Shelby County and Gentry County.
