McIntosh County, anchored by the small city of Ashley, has delivered Republican presidential margins above 60 points in recent cycles, reflecting the heavily rural, agriculturally dependent character common to south-central North Dakota's shrinking small counties.
The Republican margin in McIntosh County reached its widest at ninety points in 1920. The margin in 2024 was sixty-five points, in line with the county's deep historical pattern.
McIntosh County's loyalty is rooted in its place. Median household income of $64,419, a 92% non-Hispanic-white share, and a population of 2,497 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 Marshall County and Allen County.
