Dodge County's small-town and agricultural character anchors one of southeast Minnesota's more reliably one-sided presidential electorates, with the 2024 margin of R+31.9 continuing a pattern of double-digit Republican advantages since at least 2012.
The Republican margin in Dodge County reached its widest at seventy-one points in 1920. The margin in 2024 was thirty-two points, in line with the county's deep historical pattern.
Dodge County's loyalty is rooted in its place. Median household income of $95,739, a 91% non-Hispanic-white share, and a population of 21,045 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 Fulton County and Lewis County.
