Mike Rounds has represented South Dakota in the U.S. Senate since 2015. Before that, he served two terms as governor (2003–2011), where he built his brand around steady administration, business friendliness, and classic Plains-state conservatism.
In the Senate, Rounds leans into national security, veterans’ care, farm and ranch priorities, rural healthcare access, and pro-growth tax and regulatory policy. He’s also been active on cybersecurity and defense modernization.
Supporters see him as calm, serious, and policy-focused. Some conservatives to his right argue he’s too aligned with party leadership on spending and too careful on the culture-war stuff.
