South Dakota's Republican Sen. Mike Rounds is seeking a sixth term in the U.S. Senate, facing independent candidate Brian Bengs, a veteran who previously ran as a Democrat in the 2022 Senate race. Polls in the state close at 8 p.m. EST, and Decision Desk HQ is providing live results.
Rounds' Long Tenure
Rounds, a former governor, has held the Senate seat since 2015. His campaign has emphasized his seniority and committee positions, which he argues benefit South Dakota's agricultural, energy, and defense interests. He has also highlighted his work on infrastructure and tribal issues.
Bengs' Independent Bid
Brian Bengs, an Air Force veteran and attorney, is running as an independent after being the Democratic nominee in 2022, where he lost to Rounds by a wide margin. His platform focuses on bipartisan cooperation, fiscal responsibility, and increasing support for veterans. He has criticized Rounds for being too aligned with party leadership, while Rounds has pointed to his record of working across the aisle.
Campaign Dynamics
The race has seen limited national attention, as South Dakota is a reliably Republican state. Rounds has out-raised Bengs significantly, and polling has shown him with a comfortable lead. However, Bengs has attempted to appeal to voters frustrated with the two-party system, and he has been endorsed by some local independents and reform groups.
In the final weeks, the candidates have sparred over issues including federal spending, agricultural policy, and the role of the federal government in land management. Rounds has touted his support for the agricultural economy and his efforts to secure funding for water projects, while Bengs has called for more oversight of federal agencies.
Election Night and Beyond
With polls closing at 8 p.m. EST, results are expected to come in quickly. The race is unlikely to affect the overall balance of power in the Senate, but it will be watched as a gauge of Republican strength in the region. The outcome will also determine whether Rounds continues his long career in Washington, where he has been involved in national security and technology issues.
