Missouri Voters Reject Republican-Drawn Congressional Map

Missouri voters rejected a congressional map drawn by Republican lawmakers, according to an Associated Press race call. The vote on Nov. 3 was on Proposition A, a statewide ballot measure. Voters defeated it 62% to 38%, according to St. Louis Public Radio.

Redistricting is the process of redrawing the boundaries of the districts that elect members of the U.S. House. The map on the ballot was passed during the 2025 legislative session. Republican lawmakers passed it to try to oust Democratic Rep. Emanuel Cleaver, and it redrew his Kansas City district. The goal of the new map was to pick up one additional U.S. House seat for Republicans.

The map was part of a national push by President Donald Trump to redraw congressional districts in the middle of the decade, ahead of the midterm elections. The Missouri Independent reported that the rejected map was backed by Trump.

The map's path to the ballot ran through the courts. Missouri's top court ruled that the Republican-backed map could not be in effect for the midterms and that voters would decide on it. The U.S. Supreme Court upheld the state court ruling.

Proposition A determined whether the map would take effect in 2028, according to the Missouri Independent. NBC News projected that voters had blocked the map from going into effect for future elections.

Cleaver won reelection on Nov. 3, according to the Associated Press race call.

Redistricting was also on the ballot in other states. Maryland voters approved a constitutional amendment that changes congressional redistricting rules. It allows Democratic state leaders to redraw districts ahead of the 2028 election. Colorado voters were deciding a constitutional amendment that would ban congressional maps that purposefully favor one political party.
