Missouri has entered the national spotlight after the state’s Republican-controlled legislature approved a controversial new congressional map, widely expected to deliver the GOP one additional U.S. House seat ahead of the 2026 midterm elections.
The Missouri Senate passed the map on September 12, 2025, following approval by the House earlier in the week.
Republican Governor Mike Kehoe is expected to sign it into law swiftly, solidifying a dramatic shift that would expand the Republican advantage from six to seven of the state’s eight House seats.
This marks the first time Missouri has carried out a mid-decade redistricting—a tactic once rare but now increasingly used in highly competitive political environments to secure partisan advantages.
What the Map Changes
At the heart of this overhaul is the carving up of Kansas City’s 5th Congressional District, currently represented by Democrat Emanuel Cleaver.
The district will be split and merged with surrounding Republican-leaning rural counties, dramatically reducing its Democratic base.
Simultaneously, the state’s 2nd Congressional District, held by Republican Ann Wagner, has been redrawn to include even more GOP-friendly suburbs, further strengthening the party’s grip.
Other districts have been slightly reshaped to consolidate Republican strongholds and dilute Democratic urban voting blocs.
Overview of Missouri’s Congressional District Shifts
| District | Current Party | Key Change | Expected Outcome |
|---|---|---|---|
| 5th (Kansas City) | Democrat | Split and merged with GOP rural areas | Likely flips Republican |
| 2nd (St. Louis suburbs) | Republican | More GOP-leaning suburbs added | Safer Republican seat |
| 1st (St. Louis city) | Democrat | Minimal change | Remains Democratic |
| 3rd–8th | Republican | Slight consolidation of GOP bases | Remain Republican |
Strategic Context Behind the Redraw
This redistricting aligns with a broader national GOP strategy to lock in congressional advantages before the 2026 midterm elections. With the U.S. House currently narrowly divided, even a single new seat could determine which party controls Congress.
Former President Donald Trump directly urged Missouri Republican senators to pass the map, calling it “much fairer and much improved.” Party leaders argue the new boundaries correct population imbalances and create more compact districts.
Missouri now joins other red-leaning states like Texas and Ohio that have already or are soon planning similar mid-decade redraws to secure additional GOP-leaning seats.
Legal Challenges and Opposition
The new map immediately triggered legal challenges from civil rights and voting rights groups, who argue it violates the Missouri Constitution and amounts to partisan gerrymandering.
Critics claim the map:
- Dilutes minority voting power, especially in Kansas City
- Undermines democratic representation by slicing apart long-standing communities
- Breaks with the traditional 10-year redistricting cycle based on the Census
A grassroots coalition is also working to place a statewide referendum on the ballot to block the map. They must collect over 100,000 valid signatures from at least six congressional districts within 90 days of the governor’s signature for it to qualify.
Potential Impact on 2026 Midterms
If upheld, the new map would likely produce a 7–1 Republican advantage in Missouri’s U.S. House delegation, compared to the current 6–2 split.
This could make Missouri one of the most solidly Republican states in the nation in terms of congressional representation.
Because the national House majority is razor-thin, this single new GOP seat could play an outsized role in shaping which party controls Congress after 2026. The move also sends a signal to other Republican-led states that mid-cycle redistricting is a viable tool to gain political ground.
Missouri’s newly approved congressional map represents a high-stakes political power play. By reshaping districts to give Republicans a clear path to an additional U.S. House seat, state leaders have set the stage for a major partisan showdown.
Supporters call the map fairer and more representative of Missouri’s population trends, while critics see it as an unconstitutional power grab that erodes democratic principles and silences urban and minority voices.
As legal battles and potential referendum efforts loom, the outcome could have sweeping consequences not only for Missouri, but for the balance of power in Washington.
