Kansas primary election is Aug. 4; advance voting is underway statewide

Kansas’ 2026 primary election is Tuesday, Aug. 4, with in-person advance voting required to have begun in every county by July 28.

The election is the next statewide voting deadline for Kansas voters. County election offices administer the voting process, and voters should confirm the details that apply to their address before voting.

What is on the primary ballot

The partisan primary will determine the Democratic and Republican nominees who will advance to the November general election.

A nonpartisan constitutional-amendment question is also slated for the primary ballot. That question is separate from the party-nomination process.

Not every voter will see the same set of contests. A voter’s ballot can vary based on county, home address and party affiliation, according to the Johnson County Election Office.

Advance voting and Election Day hours

The Kansas Secretary of State’s election calendar set July 28 as the date by which in-person advance voting had to begin in all 105 Kansas counties. Available advance-voting locations and operating hours can differ by county, so voters need to check with their county election office for local options.

For Election Day, Kansas polling places must be open for at least 12 consecutive hours. State law generally uses a 7 a.m. to 7 p.m. polling-hours framework, though counties may have permitted variations.

Voters should verify their polling location, ballot information and county-specific voting hours before going to vote. The Secretary of State directs voters to confirm local operating hours rather than relying on a statewide schedule alone.

Why the date matters

Aug. 4 is the deadline for voters choosing between advance voting, where available, and voting on primary day. The results will determine the major-party nominees for November, while voters will also decide the nonpartisan constitutional-amendment question listed for the primary.

The known next election step is the Tuesday, Aug. 4 primary. Voters who plan to cast a ballot should use county-specific election information because their location, hours and contests may not match those of voters elsewhere in Kansas.
