Kansas Republicans are weighing a scenario in which U.S. Sen. Roger Marshall resigns mid-term and seeks a role in President Donald Trump’s administration, potentially delaying when Kansas voters would choose a replacement. The concern centers on a 2025 state law that restricts how the governor fills vacancies in certain statewide elective offices, including U.S. Senate seats.
Under the 2025 law, vacancies for U.S. Senate, state treasurer and state insurance commissioner must be filled by Kansas governors by selecting from finalists endorsed by the full Legislature or by a 12-person GOP-controlled legislative committee. The law also sets timing rules for when an appointed replacement must face voters: if a vacancy is created after May 1 in an even-numbered year (such as 2026), the replacement would not appear on the ballot until two years after the vacancy year—an interpretation that could mean voters would not choose until 2028.
Political observers say the U.S. Constitution’s 17th Amendment allows states to use temporary appointments for vacant Senate seats until an election is held, but they note that the statute’s language could invite legal challenges framed as an effort to delay an election. In Kansas, candidates and strategists are already considering how the new vacancy process would apply if Marshall wins his August GOP primary and resigns afterward, shifting responsibility to Gov. Laura Kelly and the Legislature.
