Presidential Preference Primary Election Day is March 19, 2024, and the Johnson County Election Office wants to provide all the necessary information for the public.

What is a Presidential Preference Primary?

The Republican and Democratic parties have previously held a caucus to nominate their favored presidential candidates in Kansas. The state legislature has chosen to conduct a Presidential Preference Primary Election in 2024.

On March 19, voters will select their preferred candidate for the presidential nomination within their political party. The results help determine how delegates are allocated to candidates at each party's national convention, where the final nominee is officially chosen.

Am I eligible to vote?

Those affiliated with the Democratic and Republican parties will receive a ballot for their respective party. Unaffiliated registered voters can affiliate with a political party at any time, including at a polling location on Election Day. Registered voters affiliated with the Libertarian and No Labels Kansas parties are not eligible to participate in this election.

Advance voting by mail

Advance ballots must be returned by 7 p.m. on Election Day. In accordance with state law, ballots received after 7 p.m. on Election Day will not be counted. This legislation only pertains to the Presidential Preference Primary Election.

There are several ways to return an advance ballot, including ballot drop boxes, advance voting locations, and Election Day polling sites. Ballot drop boxes are open 24/7 until 7 p.m. on Election Day. Advance voting locations and hours can be found at
