South Dakota voted Republican by 29.2 points in 2024, Donald Trump taking 272,081 votes to 146,859, one of the widest state margins in the country. It is settled ground: the state has gone Republican in every presidential election since 1968, and the 2024 result moved three points further that way from R+26.2 in 2020. Sixty-one of its sixty-six counties went Republican. The reddest is Harding County, in the far northwest corner, which voted Republican by 86.1 points. Across the agricultural counties the floor sits deep, and the margins widen the farther the map runs from the cities.

The only Democratic ground is the Native American reservation. American Indian residents make up most of the 7.5 percent of South Dakotans counted outside the larger race groups, concentrated on the Pine Ridge, Rosebud, Cheyenne River, and Standing Rock reservations. Oglala Lakota County, which is Pine Ridge, voted Democratic by 70.6 points — 2,567 votes to 406 — among the widest margins of any county in the United States. Todd County, on the Rosebud Reservation, ran D+50.5; Buffalo County, on Crow Creek, D+27.3; and Dewey County, on Cheyenne River, D+12.8. Those four, plus Clay County around the University of South Dakota, are the state’s only five Democratic counties.

Everything else holds near the Republican floor, including the cities. Minnehaha County, which holds Sioux Falls and casts more than one in five South Dakota votes, is the largest county in the state and still voted Republican by 12.7 points — its narrowest ground anywhere on the urban map. Pennington County, around Rapid City, ran R+26.4, and fast-growing Lincoln County, in the Sioux Falls suburbs, R+26.5. The profile underneath is middle-income and evangelical: 31.9 percent of adults hold a bachelor’s degree, 30th of the fifty states, and the state ranks 14th in evangelical Protestant adherents. Sen. Mike Rounds (R) seeks a third term in 2026 against Democrat Julian Beaudion.
