Missouri's congressional redistricting fight has returned to the U.S. Supreme Court for a third time in a single month, and absentee voters are already casting ballots under the old map the state may be forced to abandon.
A federal appeals court issued a late ruling ordering Missouri to revive a Republican-drawn congressional map that the Supreme Court had already blocked twice, throwing the state's November elections into fresh confusion and forcing yet another emergency appeal to the nation's highest court. The 8th U.S. Circuit Court of Appeals ruled that Missouri must use the new districts, saying that reverting to the prior map would violate the U.S. Constitution because the state had already held its August primaries under the 2025 lines.
The problem: the Supreme Court halted the new map on September 10, and Missouri has been running its election, printing ballots, mailing absentee packages, opening early-voting sites, under the older 2022 districts ever since. Changing course now would scramble the votes of more than one million Missourians.
The legal whiplash started when Missouri's Republican-controlled legislature redrew the state's congressional boundaries mid-decade, a move President Trump encouraged GOP-led states to pursue to gain an edge in the midterms. The new map was designed to shift Rep. Emanuel Cleaver's Kansas City-area district sharply toward Republicans, potentially expanding the GOP's Missouri delegation from six seats to seven out of eight. The Supreme Court blocked the map twice, each time leaving in place a Missouri Supreme Court decision that said the new districts could not take effect unless voters approved them in a statewide referendum.
The Missouri Supreme Court sided with People Not Politicians, a left-wing group that argued the legislature's mid-decade redraw required voter approval. That ruling forced the state back to its 2022 map, the lines drawn after the last census, which give Republicans a 6-2 advantage rather than the 7-1 split the new map would create.
Justice Brett Kavanaugh rejected an emergency appeal from Missouri Secretary of State Denny Hoskins earlier that same week, declining to refer it to the full court. Kavanaugh sided with the Missouri Supreme Court's reasoning and let the old map stand.
Then the 8th Circuit stepped in with what CBS News described as an "unusual" ruling, ordering a last-minute return to the GOP-friendly map, even after the Supreme Court had already halted exactly that move. The appeals panel directed a lower court to issue a permanent injunction requiring the 2025 districts for November.
Opponents of the new map immediately appealed to the Supreme Court, which gave supporters of the 2025 districts until midday Wednesday to respond. The urgency is not abstract. Absentee ballots using the 2022 map have already been printed and mailed. In-person early voting has begun.
Attorneys for People Not Politicians put the logistical reality bluntly in their filing, as Just The News reported:
"Ballots using the 2022 map have been printed and mailed, and absentee voting, both by mail and in-person, began today. Those ballots cannot be reassigned to new districts now."
County clerks across Missouri have warned that switching maps at this stage would be "practically impossible" and would cost hundreds of thousands of dollars. The August primaries were already held under the 2025 lines, which means the state conducted one election under one set of boundaries and could be forced to hold the general election under a different set, or whichever set the Supreme Court ultimately picks.
Richard von Glahn, executive director of People Not Politicians Missouri, framed the stakes in stark terms:
"Ballots have been printed, and Missourians have already voted. Thousands more will vote before this order seeks to take effect."
The mess deepened when a federal district judge, Chief U.S. District Judge Stephen Clark, issued a 14-day temporary restraining order directing Missouri officials to use the revised map, creating competing orders between the federal courts and the Missouri Supreme Court. Fox News reported that Missouri officials initially declared they would follow the federal order.
Missouri Attorney General Catherine Hanaway said at the time:
"Missouri is prepared to follow and comply with the federal district court's order, which binds the state to using the map enacted by the General Assembly and signed into law by Governor Kehoe."
Governor Mike Kehoe went further, declaring that the new map "will be used in the general election" after the ballot-change deadline passed. But the Supreme Court's repeated interventions have overridden that confidence each time. A lower-court ruling clearing the Republican map was itself overtaken by the state supreme court's referendum requirement.
Missouri's case is the most complex among roughly a dozen states that sought to change their U.S. House districts over the past year. Districts are normally redrawn once a decade after a census. The mid-decade push, encouraged by President Trump, broke that pattern and invited the legal tangles now playing out in real time.
The Washington Examiner noted that the August primaries were already conducted under the 2025 map, which means candidates ran and won nominations in districts that may no longer exist by Election Day. That mismatch, primary winners from one map, a general election under another, has no clean resolution.
The broader midterm landscape makes the seat math matter. Republicans hold a narrow House majority, and every district line counts. Democrats' generic ballot position trails their 2018 advantage, but individual district boundaries can override national trends.
Several open questions remain unanswered. The Supreme Court has not signaled how it will rule on this third emergency appeal. No case name or docket number has been made public in the reporting. And no one has explained how votes already cast under the 2022 map would be handled if the court orders a switch to the 2025 lines.
More than one million Missouri voters could be shuffled among districts depending on which map survives. Some have already mailed in ballots. Others are voting in person under boundaries that a federal appeals court says are unconstitutional. The state's election machinery is operating under one set of rules while courts argue over another.
The Missouri Supreme Court said the legislature's new map required a referendum. The 8th Circuit said using the old map in November after holding primaries under the new one violates the Constitution. The U.S. Supreme Court has blocked the new map twice but now faces a third appeal built on a different legal theory. Every layer of the judiciary has weighed in, and none of them agree.
When courts cannot settle a map weeks before an election, the people who pay the price are not judges or legislators, they are the voters standing in line, wondering whether their ballot will even count.
