US Supreme Court declines to reinstate Missouri GOP-backed voting map

The United States Supreme Court has declined to reinstate a Republican-backed congressional map in Missouri, leaving an older map in place for the upcoming midterm elections. On September 8, 2026, Justice Brett Kavanaugh, who handles emergency matters from Missouri, rejected the state’s request to implement the new map. He did not refer the case to the full nine-member court nor provide an explanation for his decision. This ruling presents a setback for the Republican Party, which supported the redistricting effort to enhance its electoral prospects. The proposed map aimed to improve the party's chances of securing an additional seat in the US House of Representatives by altering Missouri’s Democratic-leaning 5th congressional district. However, the legal situation remains uncertain. Following Kavanaugh’s ruling, a federal court in Missouri temporarily blocked the use of the older congressional map. US District Judge Stephen Clark, appointed by former President Trump, mandated the use of the new Republican-backed map for the November midterms, with his order remaining in effect for 14 days as courts review the dispute. Opponents of the new map have filed an appeal. The conflicting court decisions have created confusion in Missouri, with less than two months until the midterm elections. The dispute involves a congressional map approved by Missouri Republicans in 2025, aligning with a broader trend among right-leaning states, including Texas, to redraw congressional districts in favor of Republican candidates. The new boundaries would have altered the 5th congressional district, currently represented by Democrat Emanuel Cleaver, by shifting parts of it into neighboring Republican-held districts. Opponents of the redistricting effort collected hundreds of thousands of signatures to force a vote on the new map, leading to the ongoing legal battle. Missouri’s Republican officials rejected the petition as valid, resulting in a lawsuit. The Missouri Supreme Court ruled last week that the Republican-backed map must be approved by voters in a statewide referendum before it can be enacted. Kavanaugh’s decision would have upheld this ruling, but Clark’s subsequent order has added further uncertainty. Additionally, Missouri has already conducted its party primaries using the Republican-backed map, complicating the legal dynamics. Opponents argue that Republican officials dismissed the referendum petition shortly before the primary, leaving no time for an appeal. Missouri’s Republican attorney general, Catherine Hanaway, contended that reverting to the older map would disrupt the election process, given that the primary was decided with the new map. Hanaway stated that the state is prepared to comply with Clark’s order, which mandates the use of the new congressional districts. Control of the US House is at stake, with Republicans holding a narrow majority of 219 seats in the 435-seat chamber, while Democrats hold 214 seats. The race for control is expected to hinge on a few key elections. Trump’s mid-decade redistricting initiative has improved Republican prospects in approximately 16 districts nationwide, including Cleaver’s seat in Missouri, while Democrats have gained an advantage in six districts.
