Missouri General Assembly

Rule Changes

Republican majorities in both chambers; House supermajority ended in the November election; bound by Amendment 6's 80% threshold

Missouri voters rejected a constitutional amendment on Nov. 3 that would have banned abortion and written a ban on gender-affirming care for minors into the state constitution. It lost about 55% to 45%, a wider margin than the 51.6% who approved abortion rights in 2024. On the same ballot, voters passed Amendment 6, which requires 80% support in both legislative chambers before lawmakers can change or repeal a citizen-approved measure.
