Supreme Court keeps 2022 map for Missouri's November election after third intervention

September 22nd, 2026: District Court enters injunctions requiring 2025 map

Overview

Updated Sep 26

Missouri's November election will use the 2022 congressional map. The U.S. Supreme Court on September 25 stayed a federal appeals court order that would have forced the state to use the Republican-drawn 2025 map, the third time the high court has intervened.

The state Supreme Court had restored the 2022 districts on September 3 after ruling that a voter referendum on the new map must go to the ballot. A federal judge then tried to reinstate the 2025 map, but the Supreme Court blocked that order on September 10 and again on September 25. Voters will decide the map's fate as Proposition A on November 3.

Why it matters

The map was designed to hand Republicans another House seat, and conflicting court orders now leave Missouri's November election map unresolved.

  1. Ballot deadline passes with Proposition A certified

    Election Administration

    Missouri's 5 p.m. ballot deadline passed with the referendum on the GOP-drawn map listed as Proposition A. Election officials began preparing ballots under the 2025 map after Clark's order, while the 8th Circuit weighs an appeal.

  2. Missouri legislature passes new congressional map

    Legislation

    Republican lawmakers passed House Bill 1 in a special session, redrawing the state's congressional districts.

Scenarios

1

Voters approve Proposition A, new map takes effect

Possible Resolves by Nov 10, 2026

Discussed by: Republican state legislators and Trump allies quoted in The Missouri Times

Missouri voters approve the Republican-drawn map on November 3. The map takes effect 30 days after the election, so it would apply starting with the 2028 cycle. Approval would validate the legislature's redistricting push but wouldn't change the 2026 election, which will use the 2022 districts.

2

Voters reject the map, 2022 districts stay

Uncertain Resolves by Nov 10, 2026

Discussed by: People Not Politicians and redistricting reform advocates

Missouri voters reject Proposition A. The 2022 map remains in effect, and Republicans lose the extra House seat they had drawn. A rejection would mark the first time voters have overturned a congressional map since 1922 and could encourage similar referendum challenges in other states.

3

U.S. Supreme Court intervenes before the election

Unlikely Resolves by Oct 15, 2026

Discussed by: Hoskins, per Sedalia Democrat and St. Louis Post-Dispatch coverage

Hoskins files an emergency appeal arguing the state court's ruling makes timely elections impossible under federal law. If the Supreme Court grants a stay, the new map could return for November despite the pending referendum. The court would need to act by early October for the change to be practical.

4

8th Circuit blocks federal TRO, 2022 map returns for November

Possible Resolves by Sep 22, 2026

Discussed by: People Not Politicians, per STLPR

The 8th Circuit could stay or reverse Clark's order, returning Missouri to the 2022 map for November. The PAC filed an emergency appeal on September 8, arguing the state Supreme Court's ruling is the final word on which map is legal.

5

HB 1 map used for November despite pending referendum

Possible Resolves by Nov 3, 2026

Discussed by: Missouri Attorney General Catherine Hanaway and Gov. Mike Kehoe, per Democracy Docket

If Clark's order survives appeal, Missouri will hold the November election under the Republican-drawn map even though voters will also decide its fate as Proposition A. State officials say switching maps between the primary and general election would be unworkable.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

November 1922

Missouri's last congressional map referendum (1922)

Missouri voters last had a direct say on a congressional map in 1922, when voters were asked to approve or reject a legislatively drawn plan. That election established the precedent that redistricting laws could be challenged by referendum.

Then

The 1922 vote set the expectation that Missouri voters could weigh in on redistricting, though no similar referendum reached the ballot for more than a century.

Now

The precedent faded from institutional memory until this week, when the state Supreme Court revived it.

Why this matters now

The November vote is the first time since 1922 that Missouri voters will directly decide a congressional map.

June 2023

Moore v. Harper (2023)

The U.S. Supreme Court rejected the independent state legislature theory, holding that state constitutions and state courts can constrain how legislatures draw congressional maps.

Then

The decision preserved state court oversight of congressional redistricting.

Now

It affirmed that state-level rules apply to federal elections, the legal foundation for Missouri's referendum challenge.

Why this matters now

Missouri's referendum mechanism relies on this principle: state constitutional provisions governing redistricting remain enforceable.

November 2024

Ohio Issue 1 (2024)

Ohio voters approved a constitutional amendment creating an independent redistricting commission, replacing the politician-led commission that had produced maps repeatedly struck down by courts.

Then

Map-drawing authority shifted from elected officials to a citizen commission.

Now

The measure reflects a wave of voter-led redistricting reform attempts across the country.

Why this matters now

Ohio and Missouri show voters pushing back on legislative control of congressional maps through different mechanisms: constitutional amendment in Ohio, referendum in Missouri.
