The Supreme Court again blocked Missouri from using a Trump-backed congressional map, dealing a setback to Republicans before the 2026 midterms.
WASHINGTON — The Supreme Court has again blocked Missouri from using a Republican-drawn congressional map backed by President Donald Trump, dealing another setback to GOP efforts to reshape the state’s districts ahead of the 2026 midterm elections.
The justices on Thursday granted an emergency request from opponents of the map and suspended a federal judge’s order that had allowed the new boundaries to be used in November.
The unsigned order did not provide an explanation, and no justice publicly dissented. It marked the second Supreme Court rejection involving the disputed map in just three days.
Supreme Court blocks Missouri congressional map
The latest ruling keeps the Republican-backed redistricting plan from being implemented for the November general election while the legal dispute continues.
Missouri Republicans had sought to use the new map after a federal judge temporarily cleared the way for its implementation despite an earlier decision by the Missouri Supreme Court.
The U.S. Supreme Court’s intervention now leaves the state’s previous congressional boundaries in place for the 2026 election unless further legal action changes the situation.
Trump-backed map targeted Democratic seat
The disputed map was drawn by Missouri Republicans after Trump urged GOP-controlled states to pursue mid-decade redistricting that could improve Republican prospects in Congress.
In Missouri, the new boundaries were designed in part to dismantle the Kansas City-area district represented by Democratic Rep. Emanuel Cleaver.
The redrawn map was expected to give Republicans a stronger chance of winning seven of the state’s eight congressional seats, potentially helping the party protect its narrow House majority.
Missouri Supreme Court had rejected map
The dispute began in Missouri state court after opponents of the new districts submitted hundreds of thousands of signatures seeking a statewide referendum.
The Missouri Supreme Court ruled that the referendum petition was valid and that the new congressional map could not take effect unless voters approved it.
The court concluded that the state’s 2022 congressional map remained the one legally in effect for the November election and ordered the referendum to appear on the ballot.
Federal judge created new legal clash
The situation became increasingly complicated after a federal judge issued an order allowing the new Republican-favored map to be used.
That decision conflicted with the Missouri Supreme Court’s ruling and created uncertainty over which districts candidates and voters would use in November.
The dispute became particularly urgent because Missouri had already conducted its August congressional primaries under the newer map, leaving officials to navigate the possibility of changing district boundaries before the general election.
Supreme Court previously rejected Missouri appeal
Thursday’s action followed an earlier Supreme Court decision involving the same dispute.
Justice Brett Kavanaugh had previously rejected Missouri’s emergency request to revive the Republican-drawn map, leaving the Missouri Supreme Court’s decision blocking the map intact at that stage.
That ruling was already viewed as a setback for Trump and Republicans, who argued that abandoning the map after the primary could create confusion for voters and candidates.
Missouri election plans remain unsettled
The competing court rulings have created an unusual situation for Missouri election officials just weeks before the November midterms.
More than a million Missouri voters participated in the primary under the newly drawn districts, while the legal rulings have pushed the state back toward its earlier congressional boundaries.
Opponents of the map argue that the Republican plan improperly sought to manipulate congressional districts for partisan advantage. Supporters contend that changing the map after the primary could undermine voters who participated under the new boundaries.
Setback for Trump’s redistricting strategy
The Missouri fight is part of a broader national battle over congressional redistricting that intensified after Trump encouraged Republican-led states to redraw maps during the current election cycle.
Republicans have argued that mid-decade redistricting can strengthen their position in the House, while Democrats and voting-rights groups have challenged several of the efforts.
The Missouri ruling represents a significant legal obstacle to that strategy because the map was specifically designed to improve Republican prospects in a closely divided House.
What happens next
For now, Missouri’s older congressional map remains positioned to govern the November general election, while the fate of the newer map could ultimately be decided by voters through the statewide referendum.
The Supreme Court’s latest order provides an immediate answer to the question of which map can be used while the legal fight continues, but it does not end the broader dispute.
With the midterm elections approaching, Missouri remains at the center of a high-stakes battle over redistricting, election administration and the balance of power in the U.S. House.
