Redistricting in Missouri ahead of the 2026 elections
Redistricting is the process of enacting new district boundaries for elected offices, particularly for offices in the U.S. House of Representatives and state legislatures. This article covers redistricting activity in Missouri after the 2024 elections and before the 2026 elections.
Gov. Mike Kehoe (R) signed new congressional district boundaries into law on September 28, 2025. The districts take effect for the 2026 elections.[1] The Missouri Senate approved new congressional district boundaries by a 21-11 vote on September 12, 2025.[2] The Missouri House approved the map by a 90-65 vote on September 9, 2025.[3] The map aimed to net one additional Republican U.S. House district by drawing parts of Kansas City into surrounding rural districts.[4][5] Heading into the redistricting effort, Republicans represented six of Missouri's congressional districts, and Democrats represented two. Gov. Mike Kehoe (R) called the special legislative session for congressional redistricting on August 29, 2025.[4] The special session began on September 3, 2025.[6]

Redistricting in Missouri ahead of the 2026 elections
On August 21, 2025, Trump wrote on Truth Social, "The Great State of Missouri is now IN. I’m not surprised. It is a great State with fabulous people. I won it, all 3 times, in a landslide. We’re going to win the Midterms in Missouri again, bigger and better than ever before!"[7] On August 29, 2025, Gov. Mike Kehoe (R) announced a special session for congressional redistricting and released a proposed map that would net Republicans one U.S. House seat.[8]

National overview
As of February 2026, six states had congressional district maps that were subject to change before the 2026 elections, and six states—California, Missouri, North Carolina, Ohio, Texas, and Utah—had new congressional maps. Three states were reportedly exploring voluntary redistricting, and three states had congressional maps that were subject to change due to litigation. Before 2025, only two states had conducted voluntary mid-decade redistricting since 1970.[13]
