Ziebach County, home to the Cheyenne River Sioux Reservation, swung to a Republican margin of 2.8 points in 2024 after years of returning large Democratic margins — a shift driven almost entirely by Native American voter turnout patterns.

The county's recent history is a story of close margins. The Democratic margin reached forty-six points in 1912; the Republican margin reached forty-three points in 1920. Most other elections have been decided by single-digit points.

Ziebach County's demographics — a population of 2,377, a 27% non-Hispanic-white share, a median household income of $53,958 — situate the county close to national averages on several dimensions. The county's voting pattern over the last decade is most similar to that of Corson County and Ashland County.
