The U.S. Supreme Court on Thursday halted Missouri’s use of its newly approved Republican-drawn congressional map for the 2026 elections, issuing a stay that leaves the state’s redistricting process unresolved as officials work to finalize ballots. The high court’s intervention adds a new layer of uncertainty to an already contentious legal and political battle over the future of Missouri’s congressional representation.

At the heart of the dispute is a map approved by the Missouri Legislature and signed into law by Republican Gov. Mike Kehoe in September 2025. The map would shift the state’s congressional delegation from six Republicans and two Democrats to seven Republicans and one Democrat, further consolidating GOP power. Critics say the map was designed to favor Republican candidates and diminish Democratic representation.

The controversy began when organizers, opposed to the new map, attempted to force a statewide referendum, seeking to let voters decide whether the map should take effect. However, Missouri Secretary of State Denny Hoskins, a Republican, rejected the petition for a referendum. Hoskins argued that the state constitution does not allow such a vote on congressional redistricting plans passed by the legislature, effectively blocking the effort to put the map before voters.

The legal battle escalated when the Missouri Supreme Court rejected Hoskins’ argument last week. The court ruled that the state constitution’s language permits a referendum on any act of the General Assembly, with no exception for redistricting. This decision opened the door for the new congressional map to appear on the November ballot, giving Missouri voters the opportunity to approve or reject the legislature’s plan.

Supreme Court’s Temporary Stay

The U.S. Supreme Court’s unsigned order, issued without any noted dissents, temporarily halts a lower court directive that would have required Missouri to use its 2025 map for the upcoming elections. The justices stated that the stay will remain in effect while the appeal proceeds in the Eighth Circuit and during any subsequent petition to the Supreme Court. The details of the order are available in the official order.

Justice Brett Kavanaugh, who oversees emergency applications from the Eighth Circuit, had previously denied Missouri’s request to halt the Missouri Supreme Court’s ruling. After Kavanaugh’s denial, Chief District Judge Stephen Clark issued a temporary restraining order (TRO) in a separate lawsuit, instructing the state to use the 2025 map. Missouri officials indicated they would comply with Clark’s order, but left-leaning challengers appealed to the Eighth Circuit, which denied their request to stay the TRO. The challengers then brought the matter to the Supreme Court, resulting in Thursday’s stay.

Missouri Secretary of State Hoskins and other state officials argued in their emergency application that the Missouri Supreme Court’s ruling would create confusion and disrupt the electoral process. They said that primary winners would be forced to campaign in dramatically different districts for the general election, since the primaries had already been held under the new map. The Supreme Court’s order did not provide an explanation for its decision to pause Clark’s ruling, but the timing of the stay—just days before ballots are to be finalized—underscores the urgency and complexity of the situation.

"[The Missouri Supreme Court’s ruling] undoubtedly will require the winners of the Primary Election to run in dramatically different districts for the General Election."

The Missouri Supreme Court, in its earlier ruling, emphasized that the constitution’s “plain language” authorizes a referendum on any legislative act, including redistricting. The court found no exception for congressional maps, clearing the way for the issue to be placed before voters in November. If the referendum proceeds, Missourians will have the chance to approve or reject the new map, a rare opportunity for direct input on the state’s congressional boundaries.

The political stakes are high. If the new map is ultimately used, Republicans would likely gain an additional seat in Congress, further solidifying their hold on Missouri’s delegation. If the referendum succeeds in overturning the map, the state would need to revert to a previous map or devise a new one, potentially reshaping the balance of power.

What Happens Next

The Supreme Court’s stay will remain in effect until the high court either denies a petition for review or, if it grants review, until it issues a decision on the merits. Missouri’s ballots are expected to be finalized on Tuesday, leaving state officials and candidates in a state of uncertainty about which map will ultimately govern the 2026 congressional races. The outcome of the legal proceedings will determine whether the new map appears on the November ballot and, ultimately, how Missouri’s congressional districts are drawn for the next election cycle.

Supporters of the new map have not publicly addressed the Supreme Court’s order. For now, the state’s redistricting process remains in limbo, with the final decision resting in the hands of the federal courts. The coming weeks will be critical as legal challenges continue and election deadlines approach, shaping the future of Missouri’s representation in Congress.
