Missourians defeat Prop A, ending Trump-backed congressional map

Key Points:

• Missourians decisively rejected Proposition A, a congressional map backed by President Trump aimed at unseating Democratic Congressman Emanuel Cleaver, with 62% voting against it, preventing the map from taking effect in the 2028 election.
• The rejected map, passed in 2025, had divided Kansas City into three districts and redrawn St. Louis-area districts, following Trump’s directive to Republican-led states to redraw maps to maintain GOP control of the U.S. House.
• Legal challenges delayed the map's implementation, with courts ordering the use of a 2022 map favoring Cleaver for the 2026 election, and Republicans eventually abandoning efforts to salvage the 2025 map amid strong opposition fundraising and campaigning.
• The defeat of Proposition A coincided with significant losses for Missouri Republicans in state legislative races and the defeat of GOP Congresswoman Ann Wagner by Democrat Fred Wellman, signaling voter frustration with political maneuvering over substantive issues.
• Amendment 6’s passage, which prevents the legislature from overriding referendum results, further complicates future Republican efforts to redraw Missouri’s congressional map, though the Missouri Supreme Court has left the door open for potential redistricting attempts.
