Supreme Court Denies Missouri GOP Map Request
9/9/2026, 3:48:02 AM
The Court’s Decision
On September 8, Justice Brett Kavanaugh issued a one-sentence order refusing to stay the Missouri Supreme Court’s ruling that blocks the newly drawn congressional map. The order leaves in place the state court’s determination that the 2025 “HB 1” map cannot take effect until voters decide its fate in a statewide referendum. Missouri will therefore conduct the November election under the 2022 districts that gave Republicans six of the state’s eight House seats.
Background and Context
In September 2025 the Republican-controlled Missouri Legislature passed HB 1 to replace the post-2020-census districts. The plan would have reconfigured the Kansas City-based 5th District, held by Democratic Rep. Emanuel Cleaver, into a configuration that would give Republicans a 7-1 advantage. Opponents formed People Not Politicians Missouri and gathered more than 300,000 signatures to place a referendum on the November ballot. Secretary of State Denny Hoskins rejected the petition on August 4, arguing that the state constitution barred referenda on congressional redistricting.
Timeline
- August 4: Missouri’s primary election was held using the HB 1 map; Hoskins rejected the referendum petition.
- Early September: The Missouri Supreme Court issued a unanimous ruling blocking the new map and ordering a November referendum.
- September 8: Justice Kavanaugh denied the emergency request to lift the state court’s block, leaving the 2022 map in place for the general election.
Data and Statistics
- 1.2 million voters cast ballots in the August primary under the HB 1 map.
- 300,000+ signatures were submitted to support the referendum petition.
- The 2022 districts allocate six seats to Republicans and two to Democrats; HB 1 would have shifted the balance to seven Republican seats and one Democratic seat.
Official Statements & Responses
People Not Politicians Missouri executive director Richard von Glahn called the Supreme Court’s denial a victory for “people, not politicians,” emphasizing that voters will decide the map’s future in November.
Criticism & Opposition
Republican Rep. Bob Onder contended that the court’s ruling disenfranchised primary voters by forcing a change in district lines after the primary.
Conflicting Reports & Gaps
Analyses of the national impact of redistricting differ. Some outlets project that Republican-friendly maps in eight states could add up to 16 seats to the GOP House tally, while others estimate a net gain of nine seats. No source provides a definitive figure for how the Missouri decision alone will alter the overall House balance.
Verbatim Quote
- “The referendum petition was legal, sufficient, and timely, and the secretary incorrectly concluded otherwise,” — Judge Ginger Gooch
What’s Next
Missouri voters will encounter two questions on the November ballot: the selection of congressional candidates under the 2022 districts and a referendum on whether to adopt the HB 1 map for future elections. If the referendum passes, the new districts could be applied in subsequent cycles; if it fails, the 2022 map will remain the governing configuration.
