The Supreme Court is being asked to decide whether Missouri must use a congressional map urged by former President Donald Trump that could flip a Democratic seat and bolster Republicans in the U.S. House. Opponents filed an emergency appeal on Sept. 22 to block an 8th Circuit order reinstating the map after the Missouri Supreme Court said the map requires voter approval. The appeals court said the map should be used because it governed the primary and failing to use it would give some voters unequal influence. Supporters say consistency avoids disenfranchisement; opponents warn the order creates election-day confusion.
Supreme Court Asked Again To Decide Trump‑Backed Missouri Map That Could Flip A House Seat
The U.S. Supreme Court is seen in Washington, D.C., on September 1, 2026.
WASHINGTON — The Supreme Court is once again being asked to decide whether Missouri must implement a congressional map drawn at the urging of former President Donald Trump that would likely flip a Democratic-held seat and strengthen the Republican majority in the U.S. House.
What’s At Issue
The dispute returned to the high court after opponents filed an emergency appeal late on Sept. 22. The group People Not Politicians asked the justices to block a federal appeals court order that reinstated the contested map for the upcoming general election.
Legal Timeline
Key developments in the litigation include:
- Aug. 4: Missouri Secretary of State Denny Hoskins ruled the state constitution bars ballot measures on congressional redistricting. He announced the decision on the day of the state primary.
- Early September: The Missouri Supreme Court said state law requires voter approval before the new map can be used.
- Justice Brett Kavanaugh, who handles emergency appeals from Missouri, declined a request from state officials and the Republican Party to intervene after the Missouri court ruling.
- Hours later, a federal district judge ordered the disputed map be used; the U.S. Supreme Court temporarily paused that order.
- Sept. 21: The St. Louis-based 8th U.S. Circuit Court of Appeals issued a new order reinstating the map for the general election.
- Sept. 22: People Not Politicians filed an emergency appeal asking the Supreme Court to block the appeals court order.
Arguments From Both Sides
Supporters of the map — approved by the Missouri Legislature last year — say restoring the map preserves consistency between the primary and general elections and avoids unequal voting influence. The 8th Circuit argued the map must be used for the general election because it was used for the primary, warning that failing to do so would mean "some Missouri voters will have more say than others on who represents them in Congress." The court noted that roughly one in four Missourians are now assigned to different districts than they were for the primary.
“A lower court cannot demand the same relief this Court has stayed by cloaking it in a new order,” People Not Politicians told the Supreme Court in its appeal.
Opponents counter that the appeals court order is creating logistical confusion for election officials and voter uncertainty on both ballots and results. They also point to the Missouri Supreme Court’s ruling that state law requires voter approval before a congressional redistricting plan can take effect.
Practical Stakes
The legislatively approved map splits a Democratic-leaning district in Kansas City and would give Republicans an advantage in seven of Missouri’s eight House districts. That shift could flip a Democratic seat to Republican control and help the GOP defend its narrow House majority.
The Supreme Court’s decision on the emergency appeal will determine which map governs the general election and shape the timeline and legal rules under which Missouri votes this fall.
