Kansas voters headed to the polls on August 4, 2026, for primary elections that will narrow the field for governor, U.S. Senate, and House races, as well as decide a constitutional amendment on the state Supreme Court. Polling places were open from 7 a.m. to 7 p.m., with some counties extending hours to 8 p.m.
The gubernatorial race drew particular attention as an open seat contest. Democratic Governor Laura Kelly is term-limited and ineligible to seek a third consecutive term, leaving both parties with competitive primary fields. The Republican primary for governor featured seven candidates, including Ty Masterson, the Kansas State Senate president who received an endorsement from President Donald Trump. According to prediction markets reported on election day, Masterson held approximately 80 percent odds as the front-runner in the GOP primary.
The Democratic governor primary included three candidates. According to Kansas Reflector reporting on prediction markets, State Senator Cindy Holscher from Overland Park was favored to win the Democratic nomination with around 90 percent odds on both markets.
For the U.S. Senate, incumbent Republican Roger Marshall is running for re-election to a second term. Marshall faces a primary challenge from Arch Pond Naramore in the Republican primary. The Democratic Senate primary features a larger field of candidates competing for the nomination.
Voters across Kansas’s four congressional districts also cast ballots in House primaries. The races include both competitive primaries and uncontested races, with some incumbents running for re-election and others facing challengers within their party.
Beyond the statewide and federal races, Kansas voters decided on a constitutional amendment question regarding the Kansas Supreme Court. The amendment would allow voters to directly elect justices rather than having them appointed through the current system.
The August 4 primary is the first step in a two-stage process for Kansas elections in 2026. The general election is scheduled for November 3, 2026, when voters will choose the final nominees for governor, Senate, House, and other offices. Results from the primary were expected to become available after polls closed on election night, with the State Board of Canvassers set to certify official results by September 1, 2026.
