Missouri electorate rejects congressional map revision and expands petition rights

Missouri voters cast a split decision on two ballot measures, rejecting a proposed change to the congressional map while approving new safeguards for the petition process.

The 2022 redistricting cycle established the current district boundaries. In 2025, state lawmakers proposed a mid-decade map revision. This plan expanded the 5th District to stretch from Kansas City to Jefferson City. Republican leaders supported the shift to increase their seat count. The proposal specifically affected Gladstone and parts of Clay County, moving those areas from the 5th to the 6th District. The measure triggered a statewide debate over legislative control versus voter input.

On November 3, 2026, voters decided the fate of both initiatives. Unofficial results from the Associated Press show that more than 60 percent of voters rejected Proposition A. This outcome keeps the existing congressional district lines in place for upcoming elections. Simultaneously, Amendment 6 passed with 60 percent support. The amendment modifies the rules for placing issues on the ballot. Under the new law, citizens may still gather signatures to propose legislation. However, legislators can now only refer a proposed change to voters if 80 percent of both the House and Senate agree. Voters retain the final approval power on any such referred changes.

Richard Von-Glahn, executive director of People Not Politicians, commented on the rejection of the map. He stated, "I feel relieved, we have known this from the beginning when Missourians told the governor, told the legislature not to do this. They didn't listen, they listened to DC not the people of the state, so the people of the state just sent them a very clear defeat." The current district boundaries will remain effective as the state prepares for the next cycle of congressional elections.
