Missouri Amendment 4 initiative threshold vote

United States — Missouri voters are deciding on Amendment 4, a proposed constitutional amendment that would require citizen-initiated constitutional amendments to pass in all eight of the state's congressional districts, rather than by a simple statewide majority. This would be the toughest standard in the nation, and no other state has asked voters to consider such a requirement. The measure, referred to the ballot by Republican lawmakers, is seen as a response to recent progressive initiatives that passed with less than 53% statewide support, including abortion rights, marijuana legalization, sports betting, and Medicaid expansion. Critics argue it would undermine majority rule and one-person-one-vote principles, while supporters say it ensures broad geographic consensus. The outcome may not be final, as the Respect Missouri Voters coalition has submitted over 300,000 signatures for a counter-amendment that would protect the initiative process and require an 80% legislative vote to reverse voter-approved initiatives.
