Poll Shows Democrat Hamilton Leading Republican Marshall in Kansas Senate Race

A single Emerson College survey showing a two-point Democratic lead in a state that voted for Donald Trump by double digits in 2024 illustrates how candidate-specific factors and third-party vote...

Democratic Senate candidate Adam Hamilton holds a two-point lead over incumbent Republican Sen. Roger Marshall in Kansas, according to a new Emerson College poll released this week, as reported by the Washington Examiner.

The survey placed Hamilton ahead of Marshall within a field that also includes Libertarian candidate David Graham. Emerson College conducted the poll among 750 likely voters, with a stated margin of error of 3.6 percentage points. The margin of error means the race falls within a statistical tie.

Kansas has voted Republican in every presidential election in recent decades. In the 2024 presidential contest, Donald Trump carried the state by a margin that the Washington Examiner described as heavy, though the publication did not provide a specific percentage point figure. FEC presidential results for Kansas in 2024 show Trump received approximately 62 percent of the vote compared to roughly 33 percent for Kamala Harris, a gap of approximately 29 points.

Marshall was first elected to the Senate in 2020, defeating Democrat Barbara Bollier by a margin of approximately 53 percent to 41 percent, according to Kansas Secretary of State certified results. He previously served three terms in the U.S. House representing Kansas's 1st Congressional District, winning election in 2016, 2018, and 2020.

The presence of Libertarian candidate David Graham in the race is a material factor. The Emerson poll does not report Graham's exact share of the vote, and the Washington Examiner's summary describes him as splitting the vote without specifying his percentage. The precise Libertarian vote share is not available from the current source material. A full crosstab release from Emerson College would provide that figure.

Third-party candidates have affected Kansas federal races before. In the 2020 Senate race, no Libertarian candidate appeared on the general election ballot in Kansas, according to state election records, meaning the current three-way dynamic represents a structural difference from the prior cycle.

Hamilton's policy platform and funding sources are not detailed in the available source material. His Federal Election Commission fundraising disclosures, which are public records available at FEC.gov, would show total receipts, individual donor contributions, and any PAC support raised through the most recent filing period. Those records would allow a direct comparison with Marshall's fundraising, which is similarly available through FEC disclosures.

Marshall's fundraising history is on file with the FEC. His 2020 Senate campaign reported total receipts of approximately $6.7 million through year-end 2020 filings. His current cycle totals are available through the FEC's candidate search portal but are not reflected in the current source material.

Kansas last elected a Democrat to the U.S. Senate in 1932, when George McGill won a special election, according to Senate historical records maintained by the Senate Historical Office. The state has not sent a Democrat to the Senate in a general election since that period, making any Democratic competitive showing in a Senate race statistically uncommon based on historical results.

National political environment, candidate recruitment quality, and incumbent approval ratings are all factors that analysts use to assess competitive shifts in historically safe states, though no specific approval rating data for Marshall is cited in the current source material. Marshall's Senate office has not issued a public response to the poll as of the date of this report.

Several questions remain unanswered by available public records. The full Emerson College poll crosstabs, including Graham's exact vote share, head-to-head numbers without the Libertarian candidate, and demographic breakdowns, have not been published in full as of this writing. Hamilton's FEC filings, covering the period through the most recent quarterly deadline, would reveal whether his campaign has the financial resources to sustain a competitive race statewide. The Kansas primary results certifying Hamilton as the Democratic nominee would also be available through the Kansas Secretary of State's office, which maintains official election records.
