Missouri Congressional Map: What the Court Rulings Mean for November
On Tuesday evening, the U.S. Supreme Court declined to grant a stay requested by Missouri’s Attorney General. About 15 minutes later, a federal judge granted a temporary restraining order sought by Representative Bob Onder.
So, which map is in force now? And which map will be used in November?
Election officials are moving forward with the Missouri First Map in accordance with the federal court order. The Missouri Supreme Court’s injunction against that map remains in place, and the court is considering whether to hold the Secretary of State in contempt.
September 19 is a key practical deadline: military and overseas ballots generally must be transmitted by then, making another map change more difficult.
Proposition A, the referendum to approve the Missouri First Map, remains on the November ballot.
What did the courts decide about Missouri’s congressional map?
On September 3, the Missouri Supreme Court ruled that the referendum petition behind Proposition A suspended the Missouri First Map before it took effect. The court ordered Proposition A onto the November ballot and barred officials from using the Missouri First Map unless voters approve it. That ruling required Missouri to return to the 2022 districts for the general election, even though voters had already selected their nominees under the Missouri First Map in August.
Attorney General Catherine Hanaway sought an emergency stay that would pause the state court’s ruling. Justice Brett Kavanaugh denied that request without explaining his reasoning or referring it to the full U.S. Supreme Court. His decision left the state injunction in place.
A separate federal lawsuit was brought by Representative Bob Onder, Republican congressional nominee Rick Brattin, and two Missouri voters challenging the map change on constitutional grounds, including equal protection and the right to have their primary votes counted.
Chief U.S. District Judge Stephen Clark granted a temporary restraining order barring Secretary of State Denny Hoskins and specified members of his team from using any congressional map other than the Missouri First Map.
Clark’s order lasts 14 days unless it is extended or dissolved sooner.
Why did the federal judge protect the Missouri First Map?
Judge Clark’s order focused on the votes Missourians already cast in August. Switching maps would move voters into districts where they had no role in choosing the nominees. Candidates would face a different electorate after spending their time and campaign funds competing under the Missouri First Map.
To obtain a temporary restraining order, the plaintiffs had to establish the need for immediate relief. Clark considered four factors: irreparable harm, the balance of harms, the probability of success on the merits, and the public interest.
In his written order, Clark found a “high probability of success” on the claims involving primary-voting rights and equal protection. He concluded that changing districts after the primary would undermine votes already cast and harm voters and candidates.
That gives the plaintiffs a basis to seek protection through November.
Why is the Missouri Supreme Court considering contempt against Denny Hoskins?
The contempt dispute centers on Hoskins’s instruction to election officials to move forward with the Missouri First Map instead of pausing activity until the litigation is resolved.
Hoskins’s position is that the federal order takes precedence. The U.S. Supreme Court has held that state-law restrictions cannot prevent compliance with a federal decree enforcing federal rights. Whether that principle protects his instruction to proceed is part of the dispute.
The September 8 show-cause order requires Hoskins to explain his actions and appear for arguments on September 10. It leaves the contempt question open.
Why does September 19 matter for Missouri’s congressional map?
September 19 is the key deadline for getting ballots to military and overseas voters. Federal law generally requires states to mail their absentee ballots at least 45 days before the election. For the 2026 election on November 3, that means September 19.
Printing has to happen early enough to meet the deadlines. Missouri’s absentee-ballot statute also sets a sixth-Tuesday milestone for having absentee ballots printed and available. This year, that falls on September 22.
The practical implication is that another map change becomes substantially more disruptive once ballots reach voters. If ballots go out under the Missouri First Map, switching districts could require addressing ballots already delivered or returned and preparing replacements.
Federal law allows a hardship waiver of the transmission deadline in certain circumstances, including ballot delays caused by litigation, provided voters still have enough time to participate.
Proposition A remains on the November ballot. Voters’ decision on whether to approve the Missouri First Map for future elections is separate from the immediate court fight over which districts election officials use this November.
