Missouri Supreme Court Blocks Trump-Backed Congressional Map Ahead of 2026 Midterms
9/5/2026, 8:28:08 PM
Core Event
The Missouri Supreme Court issued a unanimous ruling that the congressional map enacted in September 2025 and backed by President Donald Trump cannot be used in the November 3, 2026 general election. The court ordered that the map remain suspended until Missouri voters decide its fate in a statewide referendum.
Background & Context
The 2025 map, known as HB 1, was drawn to give Republicans a 7-1 advantage in the state’s six House seats, up from the 2022 map’s 6-2 split. In December 2025, the advocacy group People Not Politicians submitted a petition with more than 300,000 signatures—about 3.3 % of the electorate—seeking a voter referendum on the new districts. Secretary of State Denny Hoskins rejected the petition on August 4, arguing that the state constitution barred referenda on congressional redistricting. A lower court upheld Hoskins, but the Missouri Supreme Court reversed, citing the constitution’s explicit allowance for such petitions.

- Targeted district: Missouri’s 5th Congressional District, currently represented by Democrat Emanuel Cleaver, was reshaped to incorporate more rural, Republican-leaning areas.
Official Statements & Responses
- Attorney General Catherine Hanaway called the ruling a “full-fledged constitutional crisis” and urged the U.S. Supreme Court to intervene.
- Solicitor General Louis J. Capozzi warned that reverting to the old map would disrupt absentee-ballot mailing timelines and require a massive overhaul of election databases.
- Governor Mike Kehoe said the decision “undermines the legislative process.”
- President Donald Trump denounced the ruling on social media as “horrible, ridiculous, and unConstitutional.”
Criticism & Opposition
- Grant Christensen, a Jefferson City resident who signed the petition, said, “Gerrymandering is the same as voter suppression.”

- “These arguments are particularly misplaced given the secretary’s delay created the confusion, expense, and practical difficulties of which he complains,” — Judge Ginger Gooch
What’s Next
Missouri’s emergency petition asks the U.S. Supreme Court to stay the state Supreme Court’s order. The Court has been given until September 14 to respond. If the stay is denied, the 2026 general election will use the 2022 congressional map, and the referendum will determine whether the 2025 map can ever be implemented.
