Signal Supreme Court blocks Missouri's GOP-favoring congressional map for second time

Summary

The US Supreme Court blocked Missouri's newly drawn Republican-favoring congressional map from being used in the November midterm elections through an unsigned order issued on September 10, 2026. It was the second such block within a week, and no dissents were noted. The order stayed a ruling by federal district judge Stephen Clark that would have allowed the new map's use despite the Missouri Supreme Court having reached the opposite conclusion. The Court granted this relief in response to an emergency request from People Not Politicians, a group led by activist Richard von Glahn. As a result Missouri is now likely to keep using its 2022 map, which holds six Republican and two Democratic seats, instead of the new map designed to add a Republican-favorable seat. The case reaching the Supreme Court twice in one week reflects how intense the legal fights over mid-decade redistricting have become ahead of the midterms.
