KANSAS CITY, Mo. — After a dizzying legal battle that drew national attention, Missouri’s map fight is now headed to the ballot box.

Missouri voters will decide Nov. 3 whether to approve or strike down a gerrymandered congressional map lawmakers passed last year. The measure, called Proposition A, will mark the culmination of a fight that threw the state, its voters and election officials into uncertainty.

At the center of the vote is a congressional map Republican lawmakers passed outside of the normal redistricting process under pressure from President Donald Trump. The map, called HB 1, carves Kansas City voters in three GOP-leaning districts in the hopes of securing for Republicans seven of the state’s eight congressional districts.

A campaign called People Not Politicians collected more than 300,000 signatures to force a statewide referendum vote on the map. That vote will determine whether the map, which is currently blocked, can be used in future elections.

What does Proposition A say?

Do the people of the state of Missouri approve the act of the General Assembly entitled “House Bill No. 1 (2025 Second Extraordinary Session),” which repeals Missouri’s existing congressional plan, and replaces it with new congressional boundaries that keep more counties intact?

State and local governmental entities estimate no costs or savings.

What would a ‘yes’ vote mean?

A “yes” vote on Proposition A would approve the Republican-backed congressional map lawmakers passed last year.

If approved, the new map would take effect 30 days after the Nov. 3 election. Lawmakers would then represent those new districts in Congress.

In other words, supporters of the Trump-backed map want voters to say “yes” to Proposition A.

What would a ‘no’ vote mean?

A “no” vote would strike down the new Trump-backed map. Missouri would keep using a map lawmakers passed in 2022 and later used in the 2022 and 2024 elections.

Missouri is also poised to use the 2022 map in the Nov. 3 election regardless of the results on Proposition A.

People Not Politicians, which fought to place the referendum on the ballot, wants voters to say “no” to Proposition A.

How did we get here?

Lawmakers passed the new map during a special session last year in the hopes of forcing Democratic U.S. Rep. Emanuel Cleaver out of office.

Shortly after, People Not Politicians gathered hundreds of thousands of signatures to strike the map down using the state’s referendum process. The process, a form of direct democracy, allows citizens to challenge state laws at the ballot box.

A series of lawsuits, courtroom fights and contradictory legal decisions followed. At every turn, Republican state officials fought to keep the map in place.

Republican Secretary of State Denny Hoskins, for example, rejected the referendum from the ballot and Missouri held its primary election using the 2025 map.

The Missouri Supreme Court ultimately blocked the map in a unanimous decision last month that found that Hoskins was wrong to reject the referendum. The court ruled that the map could not take effect unless voters approved it in a statewide vote on Nov. 3.

The map fight also played out in front of the U.S. Supreme Court on three separate occasions. Each time, the nation’s highest court ruled against the 2025 map, setting the stage for the voters to have the final say on the boundaries next month.
