South Dakota GOP Gubernatorial Runoff Sets Stage for November Contest
7/29/2026, 5:36:32 AM
Runoff Overview
South Dakota Republicans will vote in a runoff on Tuesday to choose their nominee for governor. The contest pits incumbent Gov. Larry Rhoden, who assumed office in early 2025 after Gov. Kristi Noem joined President Donald Trump’s Cabinet, against businessman Toby Doeden. The winner will face Democratic former state Sen. Dan Ahlers in the November general election in a state that has not elected a Democratic governor since the 1970s.
Primary Results and Candidate Landscape
In the June 2 primary, no candidate reached the 35 % threshold required for an outright nomination. Doeden led with about 31 % of the vote, followed by Rhoden at roughly 25 %, U.S. Rep. Dusty Johnson at 23 %, and State House Speaker Jon Hansen at about 21 % (Associated Press). Doeden’s strength came from Minnehaha County (home to Sioux Falls) and a seven-point lead in Pennington County (Rapid City). Rhoden secured his runoff spot by winning central and northwestern counties, including Meade, Lawrence and Hughes (which contains the capital, Pierre). Lincoln County, the state’s third-most populous, remains a potential battleground.
Voter Registration and Turnout
As of June 1, South Dakota had roughly 676,000 registered voters, of whom about 322,000 were active Republicans, 137,000 active Democrats, 157,000 independents, and 57,000 inactive voters (Associated Press). The June 2 Republican primary saw about 136,000 votes cast, with early and absentee ballots accounting for roughly 19 % of that total.
Election Administration and Counting Process
Only registered Republicans may vote in the runoff, though those who missed the June 2 primary are still eligible. Polls close at 7 p.m. local time (8 p.m. or 9 p.m. ET depending on the county). The Associated Press begins reporting results one minute after polls close, reached half the vote by 10:57 p.m. ET, and posted a near-final update at 3:36 a.m. ET. The AP will declare a winner only when no realistic scenario remains for a trailing candidate to close the gap. Recounts are automatic only in the event of a tie; a losing candidate may request a recount if the margin is 0.25 % or less of total votes.
Why It Matters
The runoff determines which Republican will appear on the ballot in a reliably GOP-leaning state, giving the nominee a substantial advantage over Ahlers in November. With the 2026 midterm elections 98 days away, the outcome also signals the party’s direction heading into the next national cycle.
