Missouri and Kansas Voters Reject Ballot Measures Tied to Constitutional Amendment Process and Judicial Elections

Voters in Missouri and Kansas took part in primary elections that included ballot measures on state constitutional and judicial matters. Missouri's measure would have created a tougher standard for citizen-led constitutional amendments, while Kansas's proposal would have shifted the state toward electing Supreme Court justices rather than the current selection process. Missouri also held a separate Amendment 5, which asked voters whether the state legislature should be required to phase out individual income taxes while expanding sales taxes; reporting does not clarify whether Amendment 5 and the constitutional-amendment-threshold measure were the same proposal or distinct ballot items. According to available reporting, Missouri voters rejected the proposal to make amending the state constitution more difficult, and Kansas voters rejected the plan to move to judicial elections for the Supreme Court. Missouri's primary elections on the same day included congressional primary contests, among them a rematch in the state's 1st Congressional District, though the outcome of that race was not detailed in the supplied reporting. The exact date of the vote is given as around August 4-5, 2026, based on differing publication timestamps. The current status of both rejected measures is that they did not pass, meaning no immediate change occurs to Missouri's constitutional amendment process or to how Kansas selects its Supreme Court justices. It remains unresolved from the available reporting how Missouri's Amendment 5 income-tax/sales-tax proposal fared, whether it was linked to the amendment-threshold measure, and what the final results were in the Missouri congressional primary rematch. Additional confirmed details on vote margins, turnout, and full slate of primary results were not included in the supplied sources.
