Missouri voters have blocked a Republican-drawn congressional map from taking effect for future elections through a ballot referendum, NBC News projects. The result deals a blow to Republicans who spent over a year trying to reshape one of the state's two Democratic-held districts.
Long-Running Political and Legal Battle
The vote culminates a long-running political and legal fight. Missouri is one of several GOP-led states that heeded former President Donald Trump's call for mid-decade redistricting, passing new lines last year that drew longtime Democratic Rep. Emanuel Cleaver into a heavily Republican district.
Referendum Effort and Court Challenges
In response, a group called People Not Politicians Missouri gathered more than 300,000 signatures — well above the 106,000 required — to place a veto referendum on the ballot. Legislation facing such a referendum is typically put on hold until voters weigh in, but Missouri Republicans fought to implement the map for the 2026 midterms. Secretary of State Denny Hoskins, a Republican, waited until the August statutory deadline to announce he would not certify the referendum, calling it unconstitutional. The issue bounced through state and federal courts, producing conflicting rulings. Ultimately, the U.S. Supreme Court rejected Missouri Republicans' attempts to use the redrawn map for this year's elections three times.
National Redistricting Trend
Nine states enacted new congressional maps ahead of the 2026 midterms outside the traditional decennial census process. The mid-decade redistricting battle is expected to extend into the next election cycle, with Democratic-led states continuing to counteract Trump's initial push and Republican-led states responding to a major Supreme Court ruling this year that opened the door to dismantling majority-Black districts represented by Democrats.
