The measure would have shifted Kansas City’s 5th District and given Republicans a likely 7-1 advantage in the state’s congressional delegation.
On Tuesday, Missouri voters rejected Proposition A, the Republican-backed 2025 congressional map, according to a race call by the Associated Press.
GOP lawmakers enacted the 2025 map to increase Republican representation, specifically targeting Democratic Congressman Emanuel Cleaver by splitting his Kansas City district.
Following months of legal battles, the U.S. Supreme Court and Missouri Supreme Court ruled the state's 2022 district lines must remain in place for the general election.
Cleaver secured reelection on Tuesday, while voters rejected the map 62% to 38%, denying Republicans their redistricting goal.
Although the 2025 map is blocked, Republicans could attempt to redraw districts again in 2027 or 2028, as a Missouri Supreme Court decision opened the door for future redistricting.
