Key takeaway

Missouri voters repealed the 2025 congressional map, keeping the 2022 lines for future elections.

Missouri voters rejected Missouri Proposition A by 1,278,507 votes (61.83%) to 789,236 (38.17%) with 95% of precincts reporting, on Ballotpedia's unofficial table on Wednesday 4 November⁠¹. A No vote repeals House Bill 1 (HB 1), the congressional map Republicans passed in a 2025 special session and Governor Mike Kehoe signed on 28 September 2025. States normally redraw district lines once a decade, after the census; HB 1 was a mid-decade redraw that split Kansas City across several districts and targeted the Democratic-held 5th.

The Supreme Court of Missouri suspended the map in September and sent it to voters, and the US Supreme Court then kept Missouri on its 2022 map for this election. The referendum settles what the courts left open. Trump carried Missouri, yet 61.83% of its voters rejected the map his party drew, and the repeal keeps the 2022 lines, with the 5th in its 2022 shape, for future elections too.

Deep Analysis

In plain English

Every US state draws the boundaries of its districts for the US House of Representatives, usually once a decade after the national census. In 2025 Missouri's Republican-led legislature drew a new map early, which split Kansas City between several districts. Opponents gathered signatures to put the map to a public vote, called a referendum. On 3 November voters rejected it by a wide margin, so Missouri will keep the district lines it drew in 2022.

Deep Analysis

Root Causes

Missouri lets citizens force a referendum on a new law, and a valid referendum petition suspends the law until voters decide. the Supreme Court of Missouri applied that rule to HB 1 in September, which is why the 2025 map never governed an election.

The US Supreme Court then kept Missouri on its 2022 map for this election, so the referendum was the only remaining route by which the 2025 lines could take effect.

What could happen next?

Precedent
A referendum overturned a mid-decade congressional redraw, giving opponents of such redraws in other states with referendum rights a tested route.
Consequence
Missouri's Democratic-held 5th District keeps its 2022 shape for future elections.

Different Perspectives

Missouri voters

Missouri voters rejected Proposition A by 61.83% to 38.17% at 95% reporting, repealing the 2025 map that split Kansas City. Trump carried the state, yet its 2022 lines now stay for future elections too.

Senate Leadership Fund (SLF)

SLF reported about $43.9m of independent expenditures from 27 October to 1 November, almost all against Democrats, including $12.37m against Sherrod Brown. Seven of its ten targets won; Dan Osborn lost in Nebraska and two are uncalled.

Richard Hudson, chair of the National Republican Congressional Committee

Hudson, who runs House Republicans' campaign arm, conceded North Carolina's 9th District to Richard Ojeda before any AP call. Democrats lead 10 of the state's 14 House districts on the unofficial feed.

Department of Justice (DOJ)

DOJ lost before Judge David O. Carter on 28 October and a 9th Circuit panel on 30 October on its demand to set aside 20,000 California ballots, and says it will appeal the Alaska dismissal. No court has set a ballot aside.

Senator Dan S. Sullivan

Sullivan, who trails Mary Peltola 48.2% to 47.9% on first choices, told CNN he would accept the result. DOJ's suit to stop Alaska certifying anyone but him was dismissed on 1 November.

Scott Colom's campaign

Colom's campaign estimates that about 15,000 affidavit ballots remain to be counted in a race he leads by roughly 65 to 100 votes. Those ballots count only if voters confirm their ID or eligibility by 5pm on 10 November.
