Justice Brett Kavanaugh on Tuesday denied Missouri’s emergency bid to reinstate its revised Republican-drawn congressional map, leaving the state’s 2022 district lines in place for the November 2026 general election. The denial came without comment, and without referral to the full Court.
The order ends, at least for now, a fast-moving legal fight over a redistricting plan that Missouri lawmakers approved, that the state used for its August primary, and that the Missouri Supreme Court then blocked before the general election could proceed under the new lines. Missouri voters will now cast ballots this fall using the same congressional districts drawn after the 2020 census, not the revised map designed to shift the state’s delegation from 6-2 Republican to 7-1.
For Missouri Republicans, the result is a stinging setback. For voters in the Kansas City area, where Democratic Rep. Emanuel Cleaver holds a seat the new map was designed to make more competitive for the GOP, nothing changes in November. The old lines hold.
Missouri’s legislature approved the revised congressional map as part of a broader national push to redraw districts mid-decade. President Trump backed the new lines. But opponents filed a referendum petition challenging the map, and the Missouri Supreme Court ruled last week that the petition suspended the law before it ever took effect.
The state court’s conclusion was blunt: the congressional map adopted after the 2020 census “remains in full force and effect for the November election.” Opponents of the revised map went further, telling the U.S. Supreme Court that the new districts amounted to a map that “is not the law and has never been the law.”
That ruling created an unusual situation. Missouri had already run its August primary under the revised map. Now the state court was ordering the general election conducted under different district boundaries, a scenario Missouri Attorney General Catherine Hanaway called “catastrophic.”
Hanaway’s office filed an emergency application for a stay with the U.S. Supreme Court, arguing that no court in American history had ever imposed such a remedy. The filing warned of “unprecedented chaos” and claimed the state faced “the unprecedented scenario of being forced to apply a starkly different congressional map in the 2026 General Election.”
Hanaway framed the stakes in urgent terms:
“Only this Court can prevent Missouri from being forced to disenfranchise hundreds of thousands of voters; and only this Court can ensure that Missouri hosts a timely and lawful federal congressional election.”
The state also argued that election officials were uncertain whether they could comply with the Missouri Supreme Court’s order with voting scheduled to begin within days.
Those who challenged the revised map urged the justices to reject Missouri’s request. Their response cast the emergency as manufactured rather than genuine, arguing that the Secretary of State had waited until “the last possible day” to challenge the referendum, after implementing the revised map during the primary.
Opponents told the Court it should not “reward the Secretary’s scheme to outsmart Missouri voters, Missouri law, and the Missouri Supreme Court.” They insisted the emergency application “does not present a real emergency.”
The Washington Examiner reported that the denial means the congressional map used in both the 2022 and 2024 elections remains in effect for the upcoming November contest. The Missouri Supreme Court had ruled that voters must ultimately approve the new map via a ballot measure before it can take effect, a requirement the state’s emergency appeal sought to bypass.
The Supreme Court has been active on election-related cases in recent terms, including a significant ruling on counting mail-in ballots received after Election Day that drew national attention.
Justice Kavanaugh oversees emergency applications arising from the Eighth Circuit, which includes Missouri. He denied the state’s request without written explanation and without referring the matter to the full nine-member Court. That procedural choice is significant: it means no other justice weighed in, and the denial carries no precedential weight.
But the practical effect is immediate and decisive. Missouri’s November election will proceed under district lines that give Democrats a stronger foothold in the Kansas City area than the revised map would have allowed.
Newsmax reported that Missouri faced a Tuesday deadline to finalize changes to the November ballot, which added urgent time pressure to the Supreme Court’s review. Kavanaugh had asked opponents of the map to respond by Monday, suggesting he gave the matter at least brief consideration before denying the stay.
The case fits a pattern of high-stakes election disputes landing at the Court’s doorstep on compressed timelines. Earlier this year, the Trump administration pushed the Supreme Court to intervene on mail-in ballot rules ahead of the same November elections.
The revised map was designed to do one thing clearly: turn Missouri’s 6-2 Republican advantage in its congressional delegation into a 7-1 advantage by redrawing the Kansas City-area district held by Rep. Cleaver. That objective is now shelved for 2026.
Missouri’s emergency filing claimed “hundreds of thousands of voters” would be disenfranchised without Supreme Court intervention. That figure came from the state’s own legal argument and was not independently verified.
Several questions remain open. The Missouri Supreme Court ordered a statewide referendum on the revised map, but the timeline for that vote is unclear from available reporting. If voters ultimately approve the new districts, they could take effect for future elections, but not for this November.
The case also raises broader questions about mid-decade redistricting. Missouri is not the only state where new maps have drawn legal challenges. The Arizona voter citizenship case heading to the Supreme Court reflects a similar pattern of election-law disputes reaching the high court under tight deadlines.
The identities of the specific opponents who filed the referendum petition and responded to Missouri’s Supreme Court appeal were not named in available reporting. Nor was the Missouri Secretary of State identified by name, though opponents’ filings placed that office at the center of the dispute, accusing it of strategic delay.
Missouri Republicans did everything the political playbook calls for. They passed a map through the legislature. They had the backing of the president. They ran a primary under the new lines. And then a state court, acting on a referendum petition, pulled the rug out weeks before the general election.
Hanaway’s frustration was palpable. After filing the emergency appeal, she said:
“We have just appealed yesterday’s catastrophic ruling to the Supreme Court of the United States. We look forward to the Court’s prompt review of this critical matter, as our ability to hold timely and lawful congressional elections hangs in the balance.”
The Court’s response, silence from Kavanaugh, no referral to the full bench, left Missouri with no federal avenue to pursue before November.
The outcome also illustrates how state courts have become a decisive battlefield in redistricting fights. While federal courts and the U.S. Supreme Court draw the most attention, it was Missouri’s own highest court that blocked the map, and the U.S. Supreme Court that declined to override that judgment. State supreme courts have been increasingly willing to deliver final, hard-stop rulings that shape political outcomes.
For now, Missouri’s 2022 congressional map is the law. The revised districts sit in legal limbo, awaiting a voter referendum whose date remains uncertain. And the state’s Republicans head into November with the same map they had before, one seat short of the supermajority they thought they had already won.
When you run a primary under one set of lines and a general election under another, the word for that isn’t “democracy.” It’s disorder. And the people who pay the price aren’t the lawyers or the politicians, they’re the voters trying to figure out which district they live in.
