Kansas Senate Race Tied as Hamilton Challenges Marshall
Democrat Adam Hamilton is tied with or slightly ahead of Republican Sen. Roger Marshall in the 2026 Senate race in Kansas. Early voting was underway as of Oct. 14, 2026.
Hamilton, the Democratic nominee, led Marshall in several polls. Marshall is running for re-election to a seat Republicans have held for decades. A Democrat has not won a U.S. Senate race in Kansas in nearly a century.
Both parties have directed tens of millions of dollars to Kansas in recent weeks. President Trump said Tuesday he will campaign in Wichita next week for Marshall and other Republicans.
The change is sharp on paper. Trump earned 57% of the vote in Kansas in 2024. Kansas is described as a Trump plus-16 state, meaning he carried it by 16 points, but its Senate race was shifted into the toss-up category, meaning either party could win NPR.
The Cook Political Report with Amy Walter rated the Marshall-Hamilton race a toss-up KAKE. Cook earlier described Hamilton as a stronger-than-expected challenger with a moderate message.
Kansas had a Democratic governor and Republican U.S. senators as of October 2026. Gov. Laura Kelly, a Democrat, served eight years and is term-limited in 2026, so she cannot run again. The open race to succeed her matches Republican Ty Masterson, president of the Kansas State Senate, against Democratic state Sen. Cindy Holscher. Masterson leads in polls against Holscher.
Hamilton is the founding pastor of Church of the Resurrection and a Methodist pastor at a large congregation in Kansas. He calls himself an "independent-minded Democrat" and a moderate, distinct from Democrats in New York or Los Angeles. Former Republican Kansas governors Mike Hayden and Bill Graves endorsed Hamilton.
Marshall is a first-term Republican senator and an obstetrician, a doctor who delivers babies. He won his first Senate race by more than 11 percentage points. His campaign said Hamilton is too liberal and said he would hurt Kansas cattle, agriculture, oil and gas industries.
Recent surveys show a close margin with a clear split by gender. An Emerson College/Nexstar Media survey of 750 likely voters in September 2026 put Hamilton at 45% support and Marshall at 43% TIME. A Trafalgar Group poll tied Marshall and Hamilton at 44%-44%.
In an October 2026 Kansas Senate poll reported by KMBC, Marshall led Hamilton among men 51% to 45.6%. Hamilton led Marshall among women 49.4% to 42.4% KMBC.
Money is moving with the ratings. Senate Republicans moved campaign cash from North Carolina to Kansas as the battle for the Senate majority shifted PBS. Earlier filings show Marshall raised $553,000 in the second quarter and had $5.3 million in cash in the bank. That was more than double Hamilton's cash in the bank at that point.
Early voting is underway. That matters for the get-out-the-vote operations, known as field programs, on both sides.
The broader context here is about allocation of resources. A toss-up in Kansas does not change the governor's race, where Republicans remain favored. But it forces both Senate committees to spend in territory they did not budget for in the spring. For Republicans, a Trump visit to Wichita could help turnout in the west and south. For Democrats, the Hamilton run tests whether a pastor with crossover endorsements and a moderate brand can hold ticket-splitters, voters who back Republicans for governor and president but a Democrat for Senate.
