The U.S. Supreme Court for a third time blocked Missouri Republicans from using their 2025 congressional map, warning a late switch would create electoral chaos.
NBC News reported that the justices on Friday shut down efforts to revive the Republican-drawn map for midterms already underway, granting an emergency application from the challengers at People Not Politicians and leaving no dissents.
The election will proceed under the 2022 map, which holds six seats for Republicans and two for Democrats. The 2025 map would have eliminated one Democratic seat held by Rep. Emanuel Cleaver.
The Court blocked an Eighth Circuit ruling that had sought to put the newer map back in play. Absentee voting had already begun, and the state had started sending ballots to military and overseas voters.
In its order, the Supreme Court wrote that a late reversion would “usher in electoral chaos.” It stressed that the election “is not merely upcoming; it has already started,” and repeated its long caution that lower federal courts should not alter a state’s election rules on the eve of an election.
Missouri’s fight over the districts has stretched across state and federal courts for months, with voters already casting ballots under shifting guidance. The back-and-forth left officials and campaigns scrambling over which lines would count in November.
Under state law, a statute subject to referendum stays suspended until after the vote. Signature gatherers moved to put the new map on hold. Missouri Secretary of State Denny Hoskins delayed a call on the referendum’s legitimacy until the eve of the primary, then rejected the proposal and ordered the 2025 map used.
The Missouri Supreme Court quickly found no grounds to reject the referendum, put the new map on hold, and required the 2022 districts. It also held Hoskins in contempt. A May opinion from the state high court had already made clear the new map would not take effect ahead of the 2026 elections.
The August primary still went forward amid the dispute over the 2025 lines. That set up the later clash over whether the general election had to match the primary map.
On Sept. 4, Republican nominee Rick Brattin, Rep. Bob Onder, and two voters filed a new lawsuit seeking to restore the Republican-drawn map. U.S. District Judge Stephen Clark ruled the new map should be used. The St. Louis-based Eighth Circuit then backed that approach on Monday, saying in part that the primary had already used the 2025 map.
That appeals ruling never took effect. The Supreme Court stepped in and overturned it, returning the race to the older districts in a sequence covered as Missouri’s map fight reached the justices again while voting continued.
The emergency application came from People Not Politicians. The Supreme Court granted it and blocked the Eighth Circuit’s attempt to revive the 2025 lines. The justices noted Hoskins “was well aware that conducting the August primary election with the 2025 map carried significant risks,” pointing back to the state high court’s May opinion.
The full order is available in the Court’s posted disposition. Its core point was timing: once ballots are moving and an election has started, forcing a map change invites disorder.
That focus on late intervention echoes earlier rounds in which the high court already checked the same Missouri map fight, including when the Supreme Court blocked the GOP-drawn map a second time.
Cleaver, whose district the 2025 map would have erased, told NBC News by phone Friday he was “very happy” and glad the question was settled for November. He said his campaign would work to inform voters.
Cleaver said:
"It lasted much too long, but it’s over now,"
He added:
"The manufactured chaos, you know, has at long last ended, been brought to a final state, and we can move on."
Richard von Glahn, executive director of People Not Politicians Missouri, cast the outcome as a rebuke of the map’s sponsors.
Von Glahn said:
"We are done with corrupt politicians trying to force their map into effect outside the process outlined in the Missouri constitution,"
He also said:
"We have said from the beginning, people, not politicians will be the final deciders on this DC power grab."
Missouri Gov. Mike Kehoe, a Republican, posted on X that the ruling was “disappointing” because the general election will now use a different map than the primary.
Kehoe wrote that voters “deserved consistency and certainty, and not for the rules to be changed between elections.” He added that Missouri “will follow the Court’s order.”
His consistency point lands on real ground. Primary voters and candidates operated under one set of lines. November voters will face another. That gap is exactly what late court orders produce when map fights drag into ballot season.
Republicans had drawn the 2025 map as part of a broader push in several states to reshape districts before the midterms. Democrats in places such as California answered with their own new maps. Missouri’s version never fully stuck through the legal gauntlet.
Earlier coverage tracked how a Missouri judge cleared the Republican House map before higher courts reversed course again. Separate reporting also followed the state’s effort when the Missouri attorney general asked the Supreme Court to restore the map ahead of November.
The Missouri Supreme Court’s role remains central. It enforced the referendum suspension rule, rejected Hoskins’s attempt to keep the new map live, and held the secretary of state in contempt. Its May opinion had already signaled the 2025 lines would not govern the 2026 cycle.
Federal judges then pulled in the opposite direction. Clark’s district-court ruling and the Eighth Circuit’s Monday decision tried to lock in the newer map because the primary had used it. The Supreme Court refused to let that late federal shift stand once voting was underway.
The pattern matches prior high-court stops on the same Missouri lines, including reporting on how the justices blocked the GOP map before. Each round tightened the window and raised the cost of changing rules after ballots moved.
Practical effects are immediate. Military and overseas ballots already went out. Some absentee voting began Tuesday relative to the Court’s action. Campaigns must now educate voters on the 2022 boundaries, not the lines used in August. Cleaver keeps his district. Republicans keep six seats under the older map instead of the more favorable 2025 draw.
The Supreme Court’s emergency action is a timing ruling, not a full trial on the merits of every district line. It stops the 2025 map for this election because the contest has started and a switch would scramble the process. It does not revise Missouri’s longer redistricting law or erase the referendum fight.
Hoskins’s contempt finding and the state high court’s May warning remain on the record. So does Kehoe’s complaint that primary and general voters will face different maps. Those facts show how delayed decisions and last-minute orders leave ordinary voters with mixed signals.
People Not Politicians framed the outcome as voters prevailing over politicians. Cleaver called the fight over. Kehoe accepted the order while flagging the consistency problem. The justices put the chaos risk first and kept the 2022 map in place.
Stable election rules protect voters more than courtroom whiplash after ballots are already in the mail.
