Heading into the election, the incumbent is Roger Marshall (Republican), who was first elected in 2020.
A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. In Kansas, parties decide who may vote in their primaries. As of October 2025, the Democratic Party held an open primary and the Republican Party held a closed primary. Regardless of the party's rules, an unaffiliated voter can declare their affiliation with a party on the day of the primary and vote in that party's primary. Previously affiliated voters who want to change their affiliation to vote in a different party's primary must do so before the candidate filing deadline, which is June 1 or the next business day.[1][2]
