Missouri Supreme Court Blocks Republican Congressional Map

The Missouri Supreme Court delivered a significant decision on Thursday, halting the use of a Republican-backed congressional map for the upcoming November midterm elections. The court unanimously decreed that the new map must receive voter approval before implementation. Consequently, Missouri will revert to its previous congressional boundaries for the 2026 general election, thwarting Republican efforts to gain an additional U.S. House seat.

Former President Trump expressed strong disapproval of the ruling on Truth Social, labeling it a “Dark Day for ‘Justice’ in Missouri.” He criticized the decision as “horrible, ridiculous, and unConstitutional,” voicing concerns that the alteration in congressional districts would disrupt the election process so close to the midterms.

This decision places Missouri amidst a burgeoning nationwide conflict over congressional maps as both parties endeavor to leverage redistricting to influence control of the House. The rejected plan, supported by Trump and Missouri Republicans, sought to reshape the state’s congressional delegation to favor the GOP. Specifically, it aimed to dismantle the Kansas City-based district held by Democratic Representative Emanuel Cleaver. Cleaver lauded the court’s decision, stating, “Democracy prevails.”

Judge Ginger Gooch wrote in an opinion, “This Court reverses the circuit court’s judgment. The referendum petition was legal, sufficient, and timely, and the secretary incorrectly concluded otherwise. HB 1 did not go into effect and will not go into effect unless and until approved by the voters. The congressional redistricting the General Assembly established in 2022 remains in full force and effect for the November 2026 general election.”

Opponents of the map, particularly the organization People Not Politicians, had filed a referendum petition with adequate signatures. However, Missouri Secretary of State Denny Hoskins had dismissed it, claiming the state constitution’s referendum provisions were inapplicable to congressional redistricting. The Missouri Supreme Court overruled this assertion, deeming the petition legal, sufficient, and timely.

Missouri Attorney General Catherine Hanaway has announced plans for the Republicans to appeal the ruling to the U.S. Supreme Court. The situation remains dynamic and will be updated as more information becomes available.
