Do you support the language used in Amendment 3 regarding medical exceptions for abortion?

Missouri voters will head to the polls in November 2026 to decide the fate of Amendment 3. The measure asks the electorate to determine whether to repeal the constitutional amendment regarding reproductive healthcare rights that was approved in 2024.

Why it matters

The outcome will fundamentally alter state-level reproductive healthcare policy by either maintaining current access or repealing those rights. Proponents and opponents remain sharply divided over how the amendment impacts medical emergency protocols and legal liability for physicians.

Amendment 3 establishes a 12-week gestation limit for abortion access in cases of rape and incest. The proposal also codifies new requirements for parental consent and addresses language concerning gender-affirming care for minors.
