The Missouri House of Representatives on Tuesday approved a Republican-backed congressional map that would likely add a seat to the party’s U.S. House delegation if it becomes law, intensifying a nationwide GOP effort to protect a narrow House majority ahead of the 2026 midterm elections.
Lawmakers in Jefferson City passed the measure during a special legislative session called by Republican Gov. Mike Kehoe, who unveiled the proposed map as part of what he described as an effort to better reflect the state's conservative electorate. The plan now moves to the GOP-controlled Missouri Senate; if the Senate approves it, Gov. Kehoe is expected to sign it into law.
Republican leaders say the redistricting would align congressional boundaries with population shifts and longstanding voting patterns. Democrats objected to both the timing and the specific changes, staging a weekend sit-in in the House chamber to protest what they called an attempt to dilute Democratic representation. House Minority Leader Ashley Aune accused Republicans of seeking to "rig our maps and eliminate our representation in Congress."
The proposed map targets the Kansas City-area district held by Democratic Rep. Emanuel Cleaver by shifting its boundaries east to include more rural, right-leaning voters. If enacted, analysts and party officials say the change would likely flip Cleaver’s seat and increase Republican representation from six to seven members of Missouri’s eight-member U.S. House delegation.
Cleaver has vowed legal action if the map is signed into law. Democratic National Committee Chair Ken Martin praised Missouri Democrats’ protest and said the party would support efforts to challenge the plan. President Donald Trump posted on social media that Missouri voters would have "the tremendous opportunity to elect an additional MAGA Republican in the 2026 Midterm Elections."
Missouri’s move comes amid a broader push by Republican officials in multiple states to redraw congressional maps outside the usual post-census cycle. Hours before Missouri’s House vote, Texas Gov. Greg Abbott signed a redistricting bill passed by the state’s Republican supermajority aimed at creating additional Republican-leaning districts. Other Republican-led legislatures, including in Indiana, South Carolina and Florida, have discussed or are considering similar changes.
Nationally, the stakes are high: Democrats need a net gain of three U.S. House seats in 2026 to retake the chamber. Republicans, who currently hold a narrow majority, have argued that mid-decade redistricting is a legitimate legislative tool to address representation. Democrats and voting-rights advocates have criticized mid-decade plans as partisan gerrymanders designed to entrench incumbents.
Democratic leaders have pushed back in several states. In California, state lawmakers approved a special ballot measure that would temporarily return map-drawing authority to the Democratic-controlled legislature, an effort supported by Gov. Gavin Newsom to increase Democratic seats. Democrats in Illinois and Maryland have discussed redistricting strategies under Democratic governors J.B. Pritzker and Wes Moore to try to pick up additional seats, and courts in Ohio and Utah have ordered new maps after finding prior plans violated legal or constitutional rules.
What happens next in Missouri is procedural: the Senate must pass the House-approved map during the special session for it to reach Gov. Kehoe’s desk. Legal challenges are expected if the measure becomes law, and court proceedings could delay or modify any enacted plan ahead of the 2026 election cycle.
The Missouri action underscores how redistricting has become a central front in the battle for control of the U.S. House, with both parties using state legislatures, governors and the courts to shape the political landscape ahead of the next nationwide congressional elections.
