Newton County, anchored by Neosho in the Ozark border region, delivered a 58-point Republican presidential margin in 2024 — a spread typical of rural southwest Missouri's decades-long shift toward single-party dominance at the top of the ticket.
The Republican margin in Newton County reached its widest at fifty-nine points in 2024. The margin in 2024 was fifty-nine points, in line with the county's deep historical pattern.
Newton County's loyalty is rooted in its place. Median household income of $66,301, a 81% non-Hispanic-white share, and a population of 60,118 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 Bedford County and Fulton County.
