In Win for Missouri Voters, Supreme Court Smacks Down GOP's Rigged Map a Third Time

Although the US Supreme Court's right-wing supermajority on Friday greenlit President Donald Trump's voter purge database, it also helped deliver yet another blow to Missouri Republicans' push for a rigged congressional map.

"In 2022, the Missouri Legislature enacted a redistricting map for elections to the US House of Representatives. In 2025, the Missouri Legislature enacted a new map," says the high court's unsigned ruling. Like Republican legislators in other states, Missouri's lawmakers pursued the new districts in response to public pressure from the president.

"But under the Missouri Constitution as interpreted by the Supreme Court of Missouri, a new law such as the 2025 map does not take effect unless and until approved by voters in a referendum in the next election—at least where, as here, the number of voter signatures on the petition suffices to trigger a referendum," Friday's opinion explains.

Thus, on September 3, the document notes, "the Missouri Supreme Court ruled that the 2025 redistricting map 'is not the law and has never been the law' in Missouri—and will not take effect unless and until approved by Missouri voters by referendum in the 2026 election."

However, Missouri Republicans fought back. The following week, Justice Brett Kavanaugh—a Trump appointee and member of the court's right-wing supermajority—delivered the first blow to the 2025 map. Just days later, the full court agreed, again tossing the redrawn districts.

The high court reiterated its position for a third time on Friday, with no noted dissents: "In short, as a matter of state law, the 2022 map—not the 2025 map—must be used in the 2026 congressional election."

The justices also gave clear directions to the US District Court for the Eastern District of Missouri and the Court of Appeals for the 8th Circuit, stating that they "should not enjoin or otherwise prohibit the use of the 2022 map," and "should not order or otherwise require Missouri to use the 2025 map" in the November midterm elections.

Trump's Republican Party is trying to cling to control of both chambers of Congress in the face of the president's unpopular and illegal war on Iran, which has exacerbated the country's affordability crisis.

With early voting underway and Election Day less than six weeks away, the high court highlighted that "at this late date, ordering reversion to the 2025 map in the midst of an ongoing election would usher in electoral chaos."

Gov. Mike Kehoe—who last year called the special session to redraw the map and then signed House Bill 1—said that Friday's decision was "disappointing," but "nevertheless, Missouri will follow the court's order."

Meanwhile, Marina Jenkins, executive director of the National Redistricting Foundation, declared that "this victory is the final nail in the coffin of Missouri’s egregious mid-decade gerrymander for the 2026 midterms."

"Make no mistake: In the 2026 midterms, Missourians will not only vote on the Show Me State's 2022 congressional map, a map that keeps Kansas City together, but they will also have the opportunity to veto Republicans' egregious mid-decade gerrymander at the ballot box."

People Not Politicians Missouri, a campaign that has challenged the GOP map since it was passed a year ago and sought the latest intervention from the nation's top court, also welcomed its Friday decision.

"We are done with corrupt politicians trying to force their map into effect outside the process outlined in the Missouri Constitution," said the group's executive director, Richard von Glahn. "We have said from the beginning, people, not politicians will be the final deciders on this DC power grab. We are moving forward to vote NO on Proposition A."

Proposition A is the congressional map referendum. If enough voters oppose it, they can kill "the gerrymander that won't die," a map that targets the state's 5th Congressional District, currently held by Democratic US Rep. Emanuel Cleaver.

As The Associated Press reported Friday: "Cleaver was unopposed in the Democratic primary. Republican state Sen. Rick Brattin won a six-way Republican primary under the revised districts. They remain the candidates for the general election, even though the district boundaries have reverted to their prior lines."

Journalist Jamie Dupree called the Friday ruling a "loss for the GOP," adding that "the Missouri map will be 5R-2D instead of 6-1."
