Supreme Court Halts Missouri Redistricting Map for Midterms

The Supreme Court recently intervened in Missouri’s redistricting dispute, blocking a Republican-supported congressional map ahead of the upcoming midterm elections. Conservative Justice Brett Kavanaugh, appointed during President Trump’s first term, referred the case to the entire court. This decision stayed a federal judge’s order reinstating districts favoring Republicans. There were no dissenting opinions.

Controversial Congressional Maps

The issue involves maps drawn by Missouri Republicans that would alter the state’s eight U.S. House districts. Earlier in the week, Justice Kavanaugh had already denied an emergency appeal to reverse a ruling by the Missouri Supreme Court that halted the GOP-backed map before the midterms.

Vikram Amar, a distinguished Law Professor at UC Davis, praised the court’s action in a statement to Newsweek.

“Good for the court!”

Efforts to Block the GOP Map

The challengers to the new map, led by People Not Politicians, aimed to initiate a referendum on the redistricting plan. Richard von Glahn, the executive director of this group, emphasized the clarity of the law and the state constitution.

He stated, “The law is the law, the Missouri constitution is clear as was the Missouri Supreme Court. Over 305,000 Missouri voters—Republicans, Democrats and Independents—acted to block this political power grab last fall. People, not politicians, will have the final say when they vote NO on Proposition A this November.”

Supreme Court’s Decision

The Supreme Court’s intervention came shortly after Kavanaugh’s decision to reject the state’s initial appeal, and just days before the midterms. People Not Politicians argued in favor of using the 2022 map at the federal level during the elections. They contested that neither the Equal Protection Clause nor Article I, Section 2 guarantees voters the right to remain in the same congressional district for both primary and general elections.

The federal court’s decision was seen as disruptive, as it mandated using a map that Missouri’s highest court had determined to be unlawful.

Missouri’s Opposition

Conversely, Missouri Secretary of State Denny Hoskins argued against returning to the 2022 map post-August primary. His stance focused on preventing the constitutional rights of voters from being violated. He highlighted that potential shifts to the 2022 map would prevent many Missourians from voting for candidates they hadn’t nominated in the primary.

Election officials, already preparing ballots based on the new map, concurred with the United States’ similar arguments against switching maps between elections. This change could result in varied voter experiences across differently demarcated districts, diminishing opportunities to fully participate in electing their representatives.

The Justice Department further suggested that People Not Politicians might lack standing to pursue the appeal.

Understanding Missouri’s Redistricting Map

The central debate in Missouri revolves around whether to employ the 2022 congressional map or the districts revised by Republicans last year. The updated map potentially grants the GOP control of seven out of Missouri’s eight House seats rather than six, having already been used in August primaries.

Following legislative approval of House Bill 1 in September 2025, which altered the congressional map initiated in 2022. This bill passed comfortably before being signed into law by Republican Governor Michael Kehoe. Missouri employed the new map during its August 2026 primaries, witnessing approximately 1.2 million voters participating.
