Missouri’s Congressional Map Fight Returns to the Supreme Court
By Drooid · · How we work
The Immediate Legal Clash
On September 23 2026, People Not Politicians and its executive director Richard von Glahn filed an emergency petition with the U.S. Supreme Court asking it to keep Missouri’s 2022 congressional map for the November 3 election. Their request follows a September 21 decision by the 8th U.S. Circuit Court of Appeals that ordered the state to use the 2025 Republican-drawn map—the same districts used in the August 4 primary—citing Article I, § 2 of the Constitution. The appellate order is stayed until September 28 to give the Court time to act.
Background & Context
Missouri’s Legislature adopted a new congressional map in 2025 after a mid-decade redistricting push encouraged by President Donald Trump. The 2025 plan would shift the delegation from a 6-2 Republican advantage to a 7-1 split, eliminating the Kansas City-based district held by Democratic Rep. Emanuel Cleaver II.
A petition drive collected more than 300,000 signatures to place a referendum on the November ballot, invoking the state constitution’s “referred law” requirement. The Missouri Supreme Court unanimously ruled on September 3 that the 2025 map could not be used until the referendum passed.
Because the August 4 primary had already been conducted under the 2025 districts, federal plaintiffs—including Rep. Bob Onder and State Sen. Rick Brattin—sought a separate injunction to keep those districts for the general election. A district judge issued a temporary order favoring the 2025 map, which the Supreme Court stayed on September 10.
