Missouri Amendment 3, a legislatively referred measure on the November 3 ballot, would repeal the narrow 2024 voter-approved reproductive rights provision, impose strict limits on abortion with narrow exceptions for medical emergencies, fetal anomalies, and early rape or incest cases, and embed a permanent constitutional prohibition on gender transition procedures for minors. Trader odds hover near even because the 2024 vote passed by under three points, recent polling shows a similarly tight split among likely voters, and Republican lawmakers bundled the provisions to appeal to different priorities. Supporters highlight the constitutional lock on minor procedures already restricted by the 2023 SAFE Act, while opponents argue the language misleads on both abortion access and existing statutory protections. Late shifts in turnout among key voting blocs or final-week messaging on the measure’s exceptions could still alter the outcome before election day.
