2026 United States Senate election in Kansas

The 2026 United States Senate election in Kansas will be held on November 3, 2026, to elect a member of the United States Senate to represent the state of Kansas. Republican incumbent Roger Marshall is seeking a second term. He is being challenged by Democratic pastor Adam Hamilton.

In the August 4 primary elections, Marshall won the Republican nomination against minimal opposition. Hamilton won the Democratic nomination with 34.9% of the vote over a field of candidates that included former Kansas USDA Rural Development director Christy Davis and Army veteran Noah Taylor.

Democrats have not won a Senate election in Kansas since 1932.

Background Kansas is generally considered to be a red state, having not elected a Democrat to the U.S. Senate since 1932. Republicans control both houses of the Kansas Legislature; however, Democrats control the governorship of Kansas, which they flipped from Republican control in 2018, and held in 2022. U.S. senator Roger Marshall was elected in 2020 with 53.2% of the vote, winning by 11.4% despite expectations of a close race.

General election One issue raised during the campaign was Roger Marshall's history of suing over 700 of his patients for unpaid bills while he worked as an OB/GYN in Kansas. The New York Times reported that in at least 81 cases, patients were arrested at the request of Marshall's lawyers for failure to appear in court for their unpaid debts. There were 13 additional cases where an arrest warrant was requested, but the outcome is unknown. Most of the patients interviewed by the New York Times who were sued by Marshall said they lived paycheck-to-paycheck and did not have the money to pay the bills. Hamilton produced an advertisement featuring a woman who said she was arrested for missing a $50 payment to Marshall. The Marshall campaign sent a letter alleging the ad was "defamatory" because the woman was arrested for failing to appear in court over larger debts to him, rather than for missing one bill, and that she was subject to several other court proceedings.
