Redistricting

2020-2021

See also: Redistricting in Missouri after the 2020 census

On August 29, 2025, Gov. Mike Kehoe (R) called a special legislative session for mid-decade congressional redistricting and proposed a map that would draw parts of Kansas City into surrounding rural districts. The special session began on September 3, 2025. The Missouri House approved the maps on September 9, 2025, by a 90-65 vote.

Missouri had previously enacted new congressional district boundaries on May 18, 2022, when Gov. Mike Parson (R) signed them into law. According to Rudi Keller of the Missouri Independent, "No change in the partisan makeup of the Missouri delegation, currently six Republicans and two Democrats, is expected as a result of the map." Keller also wrote, "nine counties that have shifted almost wholly or entirely into new 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." This map took effect for Missouri’s 2022 congressional elections.

The Missouri House of Representatives approved the final version of the new congressional districts on May 9, 2022, by a vote of 101-47. Eighty-six Republicans and 15 Democrats approved the new map and 28 Democrats and 19 Republicans voted against it. The state Senate approved the legislation (known as HB 2909) on May 11, 2022, by a vote of 22-11. Sixteen Republicans and six Democrats voted to approve the new map and seven Republicans and four Democrats voted against.

After the Senate passed the maps, Keller wrote, "The first plan, released in December with backing from the Republican leaders of both chambers, essentially kept the partisan breakdown of the state’s delegation unchanged, with six safe Republican districts and two Democratic districts in Kansas City and St. Louis. The House passed that bill in January and, after weeks of on-and-off debate, the Senate passed a significantly altered version in late March. The seven members of the Senate’s conservative caucus demanded a map that cracked the Kansas City district and combined it with a huge swath of rural counties to make it possible for the GOP to capture the seat. The “6-2” vs. “7-1” debate came to a head in February when the conservative caucus began a filibuster that blocked progress not only on the redistricting plan but also on basically every other bill. At one point, two Republican Senators got into a shouting match and had to be physically separated."

How does redistricting in Missouri work? In Missouri, congressional district boundaries are drawn by the state legislature. These lines are subject to veto by the governor.

In 2018, the voters passed a citizens’ initiative called Amendment 1 that reshaped the redistricting process; in 2020, the voters narrowly passed a legislatively referred initiative called Amendment 3 that reshaped the process again.

Two distinct politician commissions are ultimately responsible for state legislative redistricting, one for the Missouri State Senate and another for the Missouri House of Representatives. Membership on these commissions is determined as follows:

“

Missouri’s congressional districts are drawn by the state legislature, as a regular statute, subject to gubernatorial veto. The state legislative lines are drawn by two separate politician commissions — one for state Senate districts, one for state House districts. For each commission, each major party’s congressional district committee nominates 2 members per congressional district, and the state committee nominates 5 members; the Governor chooses 1 per district per party and two per party from the statewide lists, for a total commission of 20.
