Supreme Court Blocks Missouri's Republican Congressional Map for a Third Time

The Supreme Court on Friday blocked Missouri Republicans from using a newly drawn congressional map in November's midterm elections, the third time in three weeks the justices have intervened in the state's redistricting fight and a decision that keeps one of the country's tightest House battlegrounds intact for now.

In an unsigned order with no noted dissents, the Court stayed a pair of lower-court rulings that would have forced Missouri to use the Republican-drawn 2025 map, and directed that the state's 2022 map govern the election that is already underway. "At this late date, ordering reversion to the 2025 map in the midst of an ongoing election would usher in electoral chaos," the justices wrote, noting that ballots have been printed and absentee and military voting has already begun.

Eight seats, two very different maps

Missouri sends eight members to the U.S. House. Under the map in force since 2022, six districts lean Republican and two are held by Democrats. The map Missouri lawmakers passed in a special session last September, and which Governor Mike Kehoe signed into law, would dismantle the Kansas City-based 5th District held by Democratic Rep. Emanuel Cleaver, pushing the delegation to 7-1. President Trump had urged the redraw explicitly for its partisan effect, saying it would "help send an additional MAGA Republican to Congress" this cycle. Missouri is one of several Republican-led states — alongside Texas and, briefly, others — that redrew House lines mid-decade this year as national Republicans sought to offset an unfavorable midterm environment; independent tallies put the potential GOP gain from the combined effort at roughly ten seats nationally, in a chamber Democrats need a net gain of only a handful of seats to flip.

How the fight reached the justices three times

Missouri's Constitution allows voters to force a referendum on new legislation, including redistricting bills, if enough signatures are gathered. A coalition called People Not Politicians collected more than 300,000 signatures against the new map, and on September 3 the Missouri Supreme Court ruled that the 2025 map "is not the law and has never been the law" until voters approve it, ordering the 2022 map used in November and setting up a statewide referendum, now known as Proposition A, on the same ballot.

What followed was a whiplash-inducing five weeks in federal court. On September 8, Justice Brett Kavanaugh, acting as circuit justice, denied Missouri's request to keep using the 2025 map. Hours later, a federal district judge issued a restraining order requiring the opposite result, which the full Supreme Court stayed on September 10 without dissent. Secretary of State Denny Hoskins briefly instructed county clerks to use the 2025 map anyway, prompting the Missouri Supreme Court to hold him in contempt before he reversed course; his office then directed election authorities statewide to use the 2022 map. On September 21, an Eighth Circuit panel tried once more to force the 2025 map into use, a ruling the Supreme Court's Friday order called an error the justices' two prior orders had already foreclosed.

Voters already casting ballots

The practical stakes fell hardest on voters in the Kansas City-area district Republicans had targeted for elimination, where Cleaver has represented Missouri's 5th District since 2005. County election officials told the courts it was "practically impossible" to revert to the 2025 lines once printing and mailing had begun, a timing problem the justices cited as central to their reasoning under the Court's long-standing rule against changing election procedures once voting is underway. Missouri Supreme Court Chief Justice Brent Powell had put the dilemma plainly during the state proceedings: officials, he said, faced a "precarious situation" in which "we just want to make sure the law is followed."

The episode also briefly turned into a test of Hoskins's own standing before the courts he was asking to rule in his favor. After he instructed county clerks on September 8 to prepare for the 2025 map even as litigation continued, the Missouri Supreme Court found him in contempt of its earlier order; the court agreed he had "purged" that contempt only after he reversed himself and recommitted to the 2022 lines days later, an unusual rebuke of a sitting statewide election official in the middle of an active election.

A split verdict in the reactions

Reaction broke almost entirely along partisan lines. Governor Kehoe called the outcome "disappointing" and "a blow to representative democracy," while Hoskins said he had "left nothing on the field" defending the new map. State Senator Rick Brattin, a co-sponsor of the redistricting push, called the ruling "a travesty for Missouri voters," and Rep. Bob Onder, whose federal lawsuit had driven the Eighth Circuit's intervention, argued that "1.2 million voters were disenfranchised" by the reversion to the older map. Missouri Attorney General Catherine Hanaway, by contrast, had told reporters before Friday's order that she saw "no legal path where the 2022 map is not used."

Cleaver, whose seat the new map would have erased, called the ruling "an act of democracy," adding, "power to the people, it is right now." Richard von Glahn, the People Not Politicians organizer whose emergency application the Court granted, put the outcome more simply.

"The law is the law, the Missouri constitution is clear, as was the Missouri Supreme Court."

What happens next

The 2022 map now governs Missouri's House delegation through the November 3 general election, with early and absentee ballots already in voters' hands. That does not end the underlying fight: Proposition A remains on the same ballot, asking Missourians directly whether to approve the 2025 map for future elections, a vote that will not affect this year's outcome but will determine whether Republicans can revive the 7-1 map for 2028 without another special session. Missouri's is one of several state-level map fights still working through courts this fall, and with control of the House expected to hinge on a small number of districts nationally, both parties are likely to keep litigating boundary lines up to Election Day and beyond.
