What happened
Republican Secretary of State delays redistricting ballot challenge ruling
Missouri's Republican Secretary of State Denny Hoskins did not issue his ruling that the state constitution does not allow ballot measures over congressional redistricting until August 4, 2026, the same day as the state's primary election. This timing prevented a legal challenge to his ruling before the primary, effectively forcing the GOP-drawn map to be used in primary voting despite the pending ballot measure.
Missouri Supreme Court rules 2025 map never became law without voter approval
The Missouri Supreme Court ruled earlier in September 2026 that the 2025 GOP-backed congressional map never went into effect as law because it had not been approved by voters through the ballot measure process. The state court blamed Republican Secretary of State Denny Hoskins for proceeding with using the GOP map in the August primary election despite knowing it required voter approval. The U.S. Supreme Court later backed this state court ruling.
Federal judge initially orders disputed GOP map to be used in election
A federal judge ruled in early September 2026 that the disputed GOP-drawn map must be used in Missouri's election, ordering it into place in a separate lawsuit filed by Republicans. The Supreme Court paused this order on September 10, but the 8th U.S. Circuit Court of Appeals reissued the order on September 21, putting the map back in place before the Supreme Court ultimately blocked it.
Supreme Court rejects Republican map after Trump-backed redistricting effort
The Supreme Court blocked a congressional redistricting plan in Missouri that was passed by state lawmakers at the behest of President Donald Trump as part of his nationwide strategy to draw more GOP-leaning seats and prevent Republicans from losing control of the House. The new map would have given Republicans an advantage in seven of Missouri's eight House districts, potentially helping Republicans gain another seat. This was the third time the Supreme Court blocked the redistricting plan.
Primary ballots cast under disputed map creates electoral inconsistency
Over one million Missourians cast primary election ballots in August 2026 using the disputed GOP-drawn congressional map, but the map was not officially approved by voters. This resulted in more than one in four Missourians being in different districts for the general election compared to the primary, meaning they did not have a say on party nominees in their current district. The federal appeals court noted that in districts where one party dominates, the primary winner is the overwhelming favorite to win the general election.
Missouri citizen petition forces congressional map to voter approval
Opponents of the 2025 GOP-drawn congressional map in Missouri, organized through a group called People Not Politicians, successfully gathered enough citizen signatures to place the redistricting changes on the November ballot as a ballot measure. This triggered a requirement under Missouri's state law that the map be approved by voters before it could go into effect. The ballot measure prevented the Republican-backed map from becoming law despite its use in the August primary election.
Supreme Court blocks GOP-drawn Missouri congressional map for 2026 election
The U.S. Supreme Court issued an unsigned order on September 25, 2026, blocking Missouri from using a 2025 congressional map in the 2026 election. The court ordered the state to use its 2022 map instead. The 2025 map had been drawn at the request of President Donald Trump and was designed to give Republicans an advantage by breaking up a Democratic-held district in Kansas City and tilting seven of eight House districts toward Republicans. The decision came after weeks of conflicting rulings between state and federal courts.
Over one million Missouri voters affected by congressional map redistricting dispute
The redistricting battle has created confusion for over a million potential Missouri voters who could be shuffled among different congressional districts. One in four Missourians are in different districts than they were in the primary election, meaning they did not have a say on party nominees in their current district.
Missouri secretary of state blocks ballot measure on congressional redistricting
Missouri's Republican Secretary of State Denny Hoskins ruled that the state's constitution does not allow ballot measures over congressional redistricting. He delayed issuing this decision until August 4, the same day as the state's primary election, which prevented a legal challenge to the new map before the primary.
Trump urges Republican-led states to undertake mid-decade congressional redistricting
President Trump spurred a wave of mid-decade redistricting efforts last year when he urged Republican-led states to redraw congressional districts to gain an edge in the midterm elections. This was unusual as districts are typically redrawn only at the start of each decade following the decennial census.
Supreme Court blocks appeals court order on Missouri congressional map
The U.S. Supreme Court paused the 8th U.S. Circuit Court of Appeals' order that would have implemented the Trump-backed Missouri congressional map. This was the second Supreme Court intervention to block efforts to use the new map in the November midterm elections.
Trump-backed Missouri congressional map returns to Supreme Court for third time
The fight over Missouri's congressional map was brought before the U.S. Supreme Court for the third time in late September after opponents of the map filed an emergency appeal. The group People Not Politicians asked the court to block the lower court's ruling that would implement the map.
Missouri legislative map redraws Democratic-held Kansas City district
The new congressional map approved by the Missouri Legislature breaks up a Democratic-held district in Kansas City, giving Republicans an advantage in seven of the state's eight House districts. The map is expected to turn the seat held by Democratic Rep. Emanuel Cleaver into one that Republicans are likely to win.
Federal appeals court orders Missouri to use Trump-backed congressional map for midterm elections
The 8th U.S. Circuit Court of Appeals issued an order on September 21 requiring Missouri to use a new congressional map backed by President Trump for the upcoming midterm elections. The court ruled that the disputed map must be used for the general election because it was used for the primary election, stating that using a different map would violate the Constitution by giving some Missouri voters more say than others in selecting their representatives.
Missouri mail-in ballots distributed using 2022 congressional map
Absentee voting is already underway in Missouri using congressional districts adopted in 2022 following the decennial census, not the new Trump-backed map. This adds complexity to the ongoing redistricting dispute as ballots have already been distributed under the previous map.
Missouri Supreme Court rules new congressional map requires voter approval
The Missouri Supreme Court ruled in early September that state law requires the new congressional map to be approved by voters in a statewide referendum before it can be used in elections. This decision was in response to the redistricting changes pushed by President Trump.
Justice Brett Kavanaugh rejects emergency appeal to block use of previous Missouri congressional map
Supreme Court Justice Brett Kavanaugh, who handles emergency appeals from Missouri, rejected a request from state officials and the Republican Party for the high court to intervene in the redistricting dispute. His rejection supported keeping the previous map in use.
Missouri Supreme Court reversed state election official's rejection of redistricting referendum petition
In September, the Missouri Supreme Court reversed Secretary of State Denny Hoskins' rejection of a referendum petition on congressional redistricting. The court barred the new Trump-backed map from being used until voters could decide on it in a November referendum, requiring the state to use the districts approved in 2022 instead.
8th U.S. Circuit Court of Appeals hears arguments on Missouri congressional redistricting
A three-judge panel of the 8th U.S. Circuit Court of Appeals held oral arguments on Thursday regarding whether Missouri should use new Republican-drawn U.S. House districts. The dispute centers on whether the state should adopt the Trump-backed map that was used in the August primary, despite the U.S. Supreme Court previously blocking these districts from being used in the November election.
U.S. Supreme Court blocked Trump-backed Missouri congressional map from November election
The U.S. Supreme Court previously blocked the enforcement of a lower court order that would have allowed Missouri to use new Republican-drawn congressional districts in the November election. Missouri is currently set to use the same congressional districts it used in 2022 and 2024.
