HB 1 fell on 3 November 2026, when Proposition A failed. Ballotpedia's unofficial table showed 1,278,507 No votes against 789,236 Yes votes. A No vote repealed the map, so the 2022 congressional lines stay in force and the Democratic-held 5th District keeps its 2022 shape.
The Republican majority in Jefferson City enacted HB 1 during a special session in 2025, and Governor Mike Kehoe put his signature to it on 28 September that year. It redrew Missouri's eight House districts mid-decade, split Kansas City across several districts and targeted the 5th. A referendum petition suspended it: on 3 September 2026 the Supreme Court of Missouri held that the petition had stripped the act of effect.
The vote is the clearest public verdict on the 2025-26 wave of Mid-decade redistricting. Donald Trump carried Missouri, yet more than three in five of its voters rejected a map his party drew.
Courts kept HB 1 out of use
After Missouri's Supreme Court suspended HB 1 on 3 September, federal courts pulled the other way. Chief Judge Stephen R. Clark ordered the state back onto the map on 8 September, and on 21 September the 8th Circuit told Missouri to use HB 1 for November before pausing its own order until 28 September.
The US Supreme Court settled the question on 25 September. It stayed the 8th Circuit's order with no noted dissent, noting that overseas ballots on the 2022 map had been in the post since 18 September. HB 1 had been drawn to elect seven Republicans and one Democrat; the 2022 map is expected to elect six and two. The act reached the 3 November ballot only as the subject of a referendum.
