Missouri’s referendum process cannot override federal constitutional protections for voters after the primary

American campaigns and voting, from primaries and general elections to the candidates, money and rules that decide them. Covers federal, state and local contests, the machinery of casting and counting ballots, and the disputes over access that follow almost every cycle.

Federal litigation over Missouri’s congressional districts pits the 2025 Republican-enacted map against the 2022 map after the Missouri Supreme Court’s September 3, 2026, referendum decision barred the newer plan. The Eighth Circuit ordered use of the 2025 map for November 3, pending Supreme Court review.
