Supreme Court blocks Missouri’s Republican-drawn map for third time, halting midterm chaos

Key points

• The US Supreme Court granted a request to suspend lower court decisions, blocking the use of a Republican-drawn congressional map in Missouri for the November 3 midterms.
• This is the third time the Supreme Court has intervened in the Missouri redistricting dispute, reversing a recent Eighth Circuit order that had mandated the new map.
• The ruling preserves the 2022 congressional map, which includes six Republican-held and two Democratic-held seats, avoiding the reshuffling of over one million voters.
• Opponents, including the ACLU and Campaign Legal Center, stated that the courts have confirmed voters, not politicians, decide representation, and that the new map was an unlawful attempt to rig the election.
• The decision arrives as absentee voting is already underway in Missouri, preventing the logistical chaos of changing district boundaries mid-election cycle.

Background

The Missouri redistricting battle has been a recurring legal dispute throughout 2026. In early September, the Missouri Supreme Court blocked the Republican-drawn map, preserving the 2020 census boundaries. However, the Eighth Circuit Court of Appeals later reversed this, ordering the state to use the new 2025 map. This led to the current Supreme Court intervention, which is the third emergency appeal in the series. The dispute threatens to shift over one million voters and has been described as a chaotic attempt by Republicans to win seven of eight House seats, while opponents argue the switch disenfranchises voters who already voted in primaries under the previous map.

How outlets are covering it

The Guardian and AP report the Supreme Court’s decision as a final block on the Republican-drawn map, emphasizing the legal victory for opponents of gerrymandering. The ACLU and Campaign Legal Center view the ruling as a confirmation that voters, not politicians, decide representation, criticizing the state’s attempt to rig the map. In contrast, the White House and Republican officials have previously defended the new map as a legitimate redistricting effort, though the current ruling undermines that position. The decision also highlights the tension between the Supreme Court’s emergency docket and the need for stable election boundaries, with Justice Ketanji Brown Jackson criticizing the court’s handling of such emergency requests in related cases.

Why it matters

The Supreme Court’s decision ensures that Missouri voters will use the 2022 congressional map for the November midterms, preventing the potential disenfranchisement of over one million voters. This ruling has national implications for redistricting disputes, as it sets a precedent for the use of emergency appeals to alter election boundaries. It also affects the balance of power in the US House, as the 2022 map includes six Republican-held and two Democratic-held seats, while the blocked map was designed to favor Republicans. The decision also underscores the importance of stable election boundaries and the role of the courts in preventing gerrymandering.

What to watch

Missouri will proceed with the November 3 midterms using the 2022 congressional map. The state’s Republican-led redistricting efforts may face further legal challenges, but the Supreme Court’s ruling provides a temporary resolution. The ACLU and Campaign Legal Center will likely continue to monitor the election to ensure that no further attempts are made to alter the map. The decision may also influence other redistricting disputes in other states, as the Supreme Court’s handling of emergency appeals is under scrutiny.
