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.
