The Missouri Supreme Court is pressing lower courts to move quickly in a pair of lawsuits that will decide whether voters get to weigh in on the state’s newly redrawn, GOP-leaning congressional map, with trial proceedings held earlier this month in Cole County Circuit Court. At stake is whether Proposition A, a referendum that would scrap the map Republican lawmakers pushed through in a 2025 special session, appears on the November 2026 ballot.
How the Fight Started
Missouri Gov. Mike Kehoe called a special legislative session in 2025 after President Trump pushed Republican-controlled states to redraw congressional lines mid-decade in an effort to protect the GOP’s narrow U.S. House majority. Lawmakers approved a map dismantling the state’s only Democratic-held district, Missouri’s 5th, centered on Kansas City. A Cole County judge ruled in March 2026 that the new map was in effect, and the Missouri Supreme Court upheld the legislature’s authority to redraw districts that same month.
The Signature Fight
Opponents responded with two separate ballot campaigns. People Not Politicians submitted more than 305,000 signatures in December seeking a public referendum on the map, while a second group, Respect Missouri Voters, submitted more than 367,000 signatures total, with roughly 330,000 going to the secretary of state’s office for a constitutional amendment. On Aug. 4, Secretary of State Denny Hoskins blocked the People Not Politicians referendum from the ballot, declaring that neither the Missouri nor federal constitution permits a public referendum on a legislative redistricting plan. People Not Politicians sued that same day.
A Second, Separate Blockage
Respect Missouri Voters filed its own suit after Hoskins similarly rejected its proposed constitutional amendment, also challenging his attempt to withdraw and rewrite a ballot title his office had certified nearly a year earlier. Records reviewed by Missouri Independent show both campaigns’ petitions had gathered enough valid signatures to qualify under state requirements, raising the central legal question of whether Hoskins had authority to block them anyway.
Inside the Courtroom
Cole County Circuit Judge Daniel Green held trials this month on both the referendum, listed as Proposition A, and the separate constitutional amendment, tracked as Amendment 6. The Missouri Supreme Court has urged Green to rule swiftly given the state’s ballot-certification deadlines, which require finalized ballot language months ahead of the Nov. 3 general election.
What Republicans Argue
State GOP officials and Hoskins have maintained that redistricting is a core legislative function under the Missouri Constitution and that allowing a public vote to undo a duly passed map would invite chaos into future map-drawing cycles nationwide, since virtually any redistricting plan could then be challenged through a referendum. They also argue the amendment campaigns are attempting an end-run around the legislature using signature-gathering machinery funded substantially by out-of-state Democratic donors.
Why It Matters Beyond Missouri
The outcome carries stakes well past Missouri’s borders. If Proposition A reaches the ballot and voters reject the GOP-drawn map, Missouri would revert to its prior lines, potentially restoring a competitive or Democratic-leaning 5th District ahead of a Congress where House control could hinge on a small number of seats. A ruling is expected within weeks, with either side likely to appeal directly to the Missouri Supreme Court given the compressed timeline before ballots must be finalized for the fall election.
