County voters will also select county commission seats and county officers including auditor, treasurer, register of deeds, and sheriff, positions that rotate onto the ballot according to the state's election cycle. No U.S. Senate seat is up for South Dakota in 2026 due to both senators being elected in different cycles. South Dakota permits no-excuse absentee voting, allowing any registered voter to request an absentee ballot by submitting an application to the Buffalo County Auditor by 5:00 PM the day before the election, though earlier requests are strongly recommended.
