Summary

The U.S. Supreme Court blocked Missouri’s attempt to use a newly gerrymandered congressional map, siding with the state supreme court which had previously ruled against Governor Mike Kehoe’s plan. This decision is seen as a setback for President Trump’s efforts to reshape electoral maps in favor of Republicans. The case stemmed from People Not Politicians’ challenge involving over 300,000 signatures gathered to reject the new map through a referendum, only to face delays and legal hurdles that allowed the gerrymandered districts to be used in August primaries before being overturned by Missouri’s Supreme Court.

Story summary

On September 3, 2026, the Missouri Supreme Court unanimously blocked new congressional districts backed by President Donald Trump from being used in the November election and ordered a statewide vote on whether to uphold or reject them. This decision came after opponents submitted over 300,000 petition signatures seeking a referendum against the map. Republican Secretary of State Denny Hoskins rejected this petition but lost his appeal at the state’s highest court. Missouri Attorney General Catherine Hanaway immediately appealed to the U.S. Supreme Court, arguing that the decision has put the state into a constitutional crisis.

Republicans had hoped these new boundaries would help them win an additional seat and maintain their slim majority in the House during the midterms. However, with less than two months before the November elections, this ruling plunges Missouri’s congressional map into uncertainty. Democrats argue that democracy prevails as more than 305,000 Missourians demanded a say on who represents them in Congress.

The conflicting rulings from different courts mean candidates who won primaries under the new map will now face the general election using the old district lines unless voters approve the new districts during November’s referendum. This decision could have significant implications for control of the closely divided U.S. House of Representatives, with legal experts and prediction markets suggesting it is more likely than not that this ruling will be upheld by the Supreme Court.

Narrative

While Trump is responsible for much of these undertakings, "the broader trend [of gerrymandering] predates Trump, and coincides with a general decay of civic norms and customs and a heightening of politics as a venture in trying to crush the enemy," Walter Olson, a legal scholar at the Cato Institute, tells Reason.

Claims (31 extracted, 7 hedged)

On Thursday, the United States Supreme Court issued a ruling in Missouri's controversial redistricting battle, backing the Missouri Supreme Court's decision that the state could not use a congressional map drafted by the state's Republican Gov. Mike Kehoe last year. uncertain
state → issue → Gov.
The Supreme Court's decision, which blocked a federal court order, is a blow to President Donald Trump's gerrymandering push, which began last August when the president urged numerous red states across the country to modify their congressional district lines to favor Republicans in the midterm elections. asserted
president → block → elections
Kehoe was happy to oblige, swiftly drawing up a new map that the Missouri Legislature approved during a special session in September 2025. asserted
Legislature → oblige → September
People Not Politicians, an anti-gerrymandering activist group, promptly challenged the new map, organizing a signature drive and petition. asserted
People → challenge → drive
They collected over 300,000 signatures from across the state and deposited them with Missouri Secretary of State Denny Hoskins in December. asserted
They → collect → December
Under Missouri's state constitution, the people "reserve power to approve or reject by referendum any act of the general assembly." asserted
people → reserve → assembly
So, once Hoskins' office had verified the signatures, implementation of the new map would be paused until a statewide vote in November could determine the gerrymander's fate. uncertain
vote → verify → fate
People Not Politicians simultaneously sued the state, claiming the Legislature lacked authority to draw up new maps between census years and that the new map violated mandates for district compactness. asserted
map → sue → compactness
The Supreme Court of Missouri disagreed, ruling in March and in May that the new map was valid. uncertain
map → disagree → May
With the group's lawsuits falling through, all hope for overturning the new map seemed to hinge on the referendum. asserted
hope → fall → referendum
However, months after the petition's deposition, Hoskins had still not certified all the signatures. asserted
Hoskins → certify → signatures
The Missouri Independent reported in May that Hoskins "said he intends to use the entire time available" up to the mandated deadline—the day of the primary election—before he would recognize the referendum as valid. uncertain
he → report → referendum
As foretold, Hoskins waited until the literal final hour before the deadline to conclude that "the referendum itself is null and void by virtue of the fact that it is unconstitutional." People Not Politicians sued again, challenging Hoskins' last-minute revelation about the referendum's constitutionality. asserted
People → foretell → constitutionality
But by then the August primary had already been conducted using the gerrymandered district lines. asserted
primary → conduct → lines
After a swift appeals process, the Supreme Court of Missouri decided against Hoskins on September 3, writing (not without some obvious irritation) "the referendum petition was legal, sufficient, and timely, and the secretary incorrectly concluded otherwise." asserted
secretary → decide → irritation
The old map, the court ruled, was to remain "in full force and effect for the November 2026 general election." asserted
court → rule → election
The next day, Missouri Attorney General Catherine Hanaway, acting on the behalf of Hoskins, appealed to the Supreme Court of the United States, asking for a stay on the Missouri Supreme Court's decision, a move that former Missouri Solicitor General Jim Layton called "unprecedented." asserted
Layton → act → that
In his new appeal to the U.S. Supreme Court, Hoskins said that the state Supreme Court could not throw out the new map because a federal election had already been conducted using it and returning to the old map would confuse voters and violate federal law. uncertain
returning → say → law
The U.S. Supreme Court denied Hoskins' request for a stay on Tuesday, effectively echoing the Missouri Supreme Court's decision. asserted
Court → deny → decision
Just minutes after the Court's denial on Tuesday, Trump-appointed federal judge Stephen Clark issued a restraining order in a different lawsuit, which blocked Missouri from "using, publishing, distributing, or mandating the use of any congressional district map other than the [new] map for the November [election]. asserted
which → appoint → ]
Choosing the court order he agreed with, Hoskins contacted Missouri election officials Tuesday night endorsing the use of the new map. asserted
Hoskins → choose → map
For this, Hoskins was summoned before the Missouri Supreme Court on Thursday to justify that his actions were not in contempt of the court's order. asserted
actions → summon → order
Just minutes before the contempt hearing began in Missouri, the U.S. Supreme Court paused Clark's restraining order while litigation in the appeals court continued. asserted
litigation → begin → court
The Missouri Supreme Court found that Hoskins' past behavior was in contempt of its order, but that his culpability would be purged if he stopped using the new map. asserted
he → find → map
Logistical challenges remain, but as of Thursday afternoon, Hoskins's office was "directing local election authorities to use the 2022 congressional map," The New York Times reports. Missouri's gerrymander is not an isolated case, nor is it a one-sided issue. asserted
it → remain → map
Over the past two years, nine states have drafted gerrymandered congressional maps. asserted
states → draft → maps
Eight of those states have Republican-controlled legislatures. asserted
Eight → have → legislatures
The ninth is California, which, at the initiation of Democratic Gov. Gavin Newsom, approved a statewide gerrymander by referendum. asserted
which → approve → referendum
While Trump is responsible for much of these undertakings, "the broader trend [of gerrymandering] predates Trump, and coincides with a general decay of civic norms and customs and a heightening of politics as a venture in trying to crush the enemy," Walter Olson, a legal scholar at the Cato Institute, tells Reason. asserted
Olson → predate → Reason
This push "to crush the enemy" might reward power-hungry politicians hoping to benefit their party, but the losers in all of this are the voters, who have their voice diluted with each further gerrymander. uncertain
voice → crush → gerrymander
Missouri's redistricting scheme may have been foiled this year, but eight other states will be using newly gerrymandered maps this November. uncertain
states → foil → maps
