Who’s on your ballot in Missouri? Let Ballotpedia help you find out.

Following the 2020 census, Missouri completed a redistricting process that changed the district maps for the U.S. House and the state legislature. Legislative redistricting in Missouri was completed on March 15 with U.S. House redistricting completed on May 18. 

According to Rudi Keller of the Missouri Independent, “nine counties that have shifted almost wholly or entirely into new [U.S. House] districts. Boundaries shifted in the five large-population counties that were previously split and a new split was introduced in Boone County in central Missouri.”

As a result of redistricting, many voters will see new names and district numbers on their ballot. Ballotpedia’s Sample Ballot Lookup tool will allow you to see changes to your ballot ahead of time and research these candidates before you go to the polls on election day.

In the Aug. 2 primary, voters throughout the state will select one candidate to serve in the U.S. Senate, eight candidates to serve in the U.S. House of Representatives, a state auditor, 17 state senators, and 163 state representatives. Clay County, Jackson County, Platte County, and the city of St. Louis have municipal positions that will be on the ballot.

Missouri has an open primary. Voters are not required to be affiliated with a political party in order to vote in that party’s primary. Voters are also able to declare any party at the polls regardless of previous party affiliation.
