Missouri's top court threw out the GOP's Trump-backed congressional map and ordered a referendum. The people's check on gerrymandering, or judges overturning a legitimate map?
The court unanimously ruled the 2025 mid-decade map illegal, reinstated the old district lines for 2026 and sent the new map to voters as Proposition A. Republicans are asking the U.S. Supreme Court to block the ruling, days before the election.
What happened
On September 3, 2026, the Missouri Supreme Court ruled unanimously that a 2025 congressional map pushed through at President Trump's direction — designed to flip the 5th District and protect the GOP's U.S. House majority — cannot be used in November because a citizen referendum against it (Proposition A) was validly certified. The court ordered the 2022-2024 district lines restored for this election. Missouri Republican officials, led by Secretary of State Denny Hoskins and AG Catherine Hanaway, immediately asked the U.S. Supreme Court to stay the ruling, arguing it would be a logistical and legal disaster this close to the election.
Why people disagree
Supporters of the ruling, including the grassroots group People Not Politicians (which gathered over 300,000 signatures) and national Democrats, argue this is exactly what referendum rights exist for: stopping a map explicitly drawn mid-decade for partisan advantage before voters get a say. Opponents argue the Missouri Constitution's referendum process shouldn't be used to freeze duly-passed legislation this close to an election, that switching maps now disenfranchises over a million primary voters and risks missing federal deadlines for overseas military ballots, and that courts are improperly inserting themselves into a legislative prerogative.
What's still unclear
It's unresolved whether the U.S. Supreme Court will grant Missouri Republicans' emergency stay request, which could restore the new map before November regardless of the state court ruling. It's also genuinely disputed whether reverting to the old map is logistically simple (as county clerks say) or technically impossible (as state officials claim) with the September 19 overseas-ballot deadline looming, and how Proposition A itself will ultimately be decided by voters.
