Missouri voters soundly rejected Amendment 4 on August 4, 2026, with over 81% voting "no" to block a Republican-led effort to restrict direct democracy. The measure would have required citizen-led constitutional amendments to win majorities in all eight congressional districts, a standard opponents warned would kill the initiative process. While Governor Mike Kehoe blamed the defeat on "special interests," defenders of the process celebrated the preservation of the state's simple-majority standard.
