Missouri Supreme Court Blocks Trump-Backed GOP House Map, Keeps Cleaver's Seat Under Old Lines

Missouri's Supreme Court unanimously ruled Thursday that the state's new Republican-drawn congressional map cannot be used in the November midterms, ordering a citizen referendum onto the ballot instead. The ruling keeps Rep. Emanuel Cleaver's Kansas City-based 5th District intact for one more election, under the maps Missouri has used since 2022.

The decision, written by Judge Ginger K. Gooch, restrains Secretary of State Denny Hoskins and anyone acting with him from "implementing, using, or mandating" the new map "unless and until" voters approve it in November and it takes effect 30 days later, according to NBC News. The old 2022 map "remains in full force and effect," the court said, according to The Hill.

How we got here

Missouri Gov. Mike Kehoe called a special legislative session in 2025 after President Trump pushed GOP-led states to redraw House lines mid-decade to protect the party's narrow majority, according to the Epoch Times. Lawmakers passed a map, known as HB 1, that stretches Cleaver's district deep into rural, heavily Republican territory. About 59% of voters in the redrawn district would have been new to it, according to an Associated Press estimate cited by Fox News. Trump would have carried the redesigned district by more than 17 points in 2024, per NBC News, versus Cleaver's actual 24-point win in his current seat.

A group called People Not Politicians gathered more than 300,000 signatures to force a statewide referendum blocking the map. Hoskins rejected the petition, arguing Missouri's constitution doesn't allow congressional redistricting to be put to a public vote. He separately threw out roughly 100,000 of the signatures, claiming they were collected before the legal window opened, according to Democracy Docket.

Cole County Circuit Judge Daniel Green sided with Hoskins on Aug. 19, ruling the referendum process "does not apply to congressional redistricting enacted by the General Assembly" and that Hoskins acted lawfully, as reported by Fox News, the Daily Wire and the Epoch Times at the time. That ruling let the new map stand for Missouri's August primary, where GOP state Sen. Rick Brattin won the nomination in the redrawn district and Cleaver ran unopposed on the Democratic side.

Plaintiffs appealed immediately. Missouri Supreme Court Chief Justice W. Brent Powell had already sent what Democracy Docket described as an unusual letter urging the lower court to move fast, after Hoskins' office sought a new judge, a move Democracy Docket characterized as one in a pattern of delay by Hoskins. The high court heard arguments this week, with a decision required before the state's Sept. 8 deadline to finalize the November ballot.

Thursday's reversal

The seven-member Supreme Court, five of whose judges were appointed by a Republican governor, unanimously found the referendum petition "legal, sufficient, and timely" and that Hoskins "incorrectly concluded otherwise," according to The Hill. That overturns Green's Cole County ruling and puts the gerrymander question directly to voters this fall.

Missouri Attorney General Catherine Hanaway said her office would "immediately" seek relief from the U.S. Supreme Court. "Never before in American history has a court overturned a congressional map after a primary and before a general election," Hanaway said, according to The Hill and NBC News, calling the ruling a "full-fledged constitutional crisis." That claim about historical precedent is Hanaway's own characterization; none of the sources independently verify it.

Missouri Democrats declared victory on social media, crediting the signature-gathering campaign, per The Hill.

The fairness question

Republicans have a real practical grievance here worth stating plainly: candidates already ran and won primaries under the new lines in August, and now the general election reverts to different boundaries days before the ballot deadline. Brattin won his nomination in a district shape that may not exist for the general election. This is a legitimate procedural mess, not a manufactured one.

On the other side, Missouri's constitution grants voters the right to referendum "any act of the general assembly" without carving out redistricting, and the state's own Supreme Court ruled the petition met every legal threshold—signatures, timing, and form. The court has protected referendum rights before, striking down signature-period restrictions in 2022, according to Democracy Docket.

What's next

Hanaway's promised appeal to the U.S. Supreme Court sets up a race against the Sept. 8 ballot-certification deadline. Fox News and the Daily Wire's earlier coverage, filed after Green's August ruling, framed the map fight as a settled GOP win. That framing no longer reflects the state of play after Thursday's reversal. Whether the U.S. Supreme Court intervenes before next week's deadline, and whether Missouri voters ultimately approve or reject the GOP map in November, remain open questions.
