Missouri Redistricting: Voters Reject GOP Map

Missouri voters rejected a congressional map drawn by Republicans on Tuesday, preventing the new boundaries from taking effect for future elections. NBC News projects that the ballot referendum will veto the lines, marking a major defeat for the party that spent more than a year attempting to redraw one of the state's two Democratic-held districts.

The vote concludes a lengthy political and legal battle over mid-decade redistricting. Missouri was among the states led by Republicans that responded to President Donald Trump's call for new maps. Last year, the state legislature approved boundaries that would have moved longtime Democratic Rep. Emanuel Cleaver into a district with a heavily Republican leaning.

Opponents of the plan organized under the name People Not Politicians Missouri. The group stated that it collected more than 300,000 signatures, a number far exceeding the roughly 106,000 required to force a public referendum. While laws subject to such referendums are typically paused until voters decide, Missouri Republicans sought to use the new map in the 2026 midterm elections.

Republican Secretary of State Denny Hoskins waited until the statutory deadline in August to announce he would not certify the referendum for the November ballot. He argued the process was unconstitutional. The dispute subsequently moved through state and federal courts, which issued conflicting decisions at various points during the year.

The U.S. Supreme Court denied efforts by Missouri Republicans to use the redrawn map for this year's elections on three separate occasions. Those rulings cleared the way for the referendum that voters decided this week. The state's conflict formed part of a national trend in which nine states enacted new congressional maps ahead of the 2026 midterms, an unusual occurrence outside the standard post-census process.

The fight over congressional lines is expected to continue into the next election cycle. Democratic-led states are pursuing efforts to counter the initial push for mid-decade changes. Meanwhile, Republican-led states are reacting to a major Supreme Court ruling this year that permitted the dismantling of majority-Black districts represented by Democrats.
