Democrat Adam Hamilton Defeats Sen. Roger Marshall in Kansas

Democrat Adam Hamilton has defeated Republican Roger Marshall in the race for a Kansas seat in the U.S. Senate, the upper chamber of Congress. The vote was held on November 3, 2026, and according to the Associated Press's tally early on Wednesday, Hamilton had won 51.1% of the ballots. The Guardian reported that his win is the first time since 1932 that a Democrat has been elected to represent Kansas in the Senate.

Marshall, 66, held the seat as the state's sitting senator, a position he has held since 2021. He previously served two terms in the U.S. House of Representatives. Hamilton, 62, leads the United Methodist Church of the Resurrection in the Kansas City area, which the same report describes as the largest United Methodist congregation in the country.

The race was closely watched. The Cook Political Report had rated it a toss-up, meaning neither candidate was considered the clear favorite. Kansas's other Senate seat is held by Republican Jerry Moran. Donald Trump won the state in the 2024 presidential election.

During a debate before the vote, Marshall said that a Hamilton victory would put Democrats in charge of the Senate. Hamilton campaigned in Overland Park on November 2 and delivered his victory speech at a hotel in that city.

The New York Times has reported that Marshall, while working as an obstetrician, sued hundreds of patients over unpaid bills. Dozens of those patients were arrested after missing court dates, the paper reported.

Kansas's elections are administered by the Secretary of State's Elections Division, led by Secretary of State Scott Schwab.
