Kavanaugh Blocks Missouri's GOP-Redrawn Congressional Map, Forcing November Referendum

Justice Brett Kavanaugh on Tuesday refused Missouri officials' emergency request to use a redrawn congressional map in the November midterm elections, deferring to a unanimous Missouri Supreme Court ruling that voters must first approve the new district lines in a statewide referendum. Kavanaugh, who oversees emergency requests from Missouri, acted alone without referring the matter to the full court and offered no written reasoning — standard practice for emergency orders.

The map at the center of the dispute was drawn outside the normal redistricting cycle at President Trump's request, explicitly designed to improve Republican odds of holding the House in the 2026 midterms. Adopted by the Missouri legislature in September 2025, it carved up the core of Kansas City — the state's largest city — into multiple districts in a calculated bid to unseat Rep. Emanuel Cleaver II, one of only two Democrats in Missouri's eight-member congressional delegation. Republicans currently hold six of those seats.

The fight escalated after Missouri Secretary of State Denny Hoskins, a Republican, refused to place a redistricting referendum on the ballot, claiming the issue couldn't legally be subject to a public vote — even though citizens had submitted 691 boxes of petitions containing more than 300,000 signatures, more than double the required threshold. Hoskins waited until after the new map was used in the August primary before formally objecting, a move opponents called a deliberate scheme to lock in the new boundaries before voters could weigh in.

Attorney General Catherine Hanaway, also a Republican, pressed the Supreme Court to allow continued use of the new map, arguing that 1.2 million Missouri primary voters had already cast ballots under it. She contended the state court's ruling effectively invalidated those votes. But Kavanaugh's refusal to intervene means Missouri will revert to its 2022 legislative map for November's general election, while voters will simultaneously be asked to approve or reject the new map via Proposition A — a referendum that opponents are already urging constituents to defeat.

The episode reflects the broader national stakes of the 2026 midterms, where control of the House may come down to a handful of seats. The Missouri maneuver was part of a coordinated Republican effort to squeeze out marginal gains through mid-cycle redistricting, and Kavanaugh's hands-off ruling — declining to identify a federal constitutional issue warranting intervention — leaves that strategy blocked, at least for now.
