Codington County anchors South Dakota's northeastern lake district, and its small-city core of Watertown hasn't softened a Republican lean that has held above 40 points in recent presidential cycles.

The Republican margin in Codington County reached its widest at forty-eight points in 1904. The margin in 2024 was forty-one points, in line with the county's deep historical pattern.

Codington County's loyalty is rooted in its place. Median household income of $72,727, a 91% non-Hispanic-white share, and a population of 28,767 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 Yankton County and Clark County.
