Missouri is the most populous state where a ballot measure could roll back a current ban on abortions at all stages of pregnancy.

Amendment 3 places language in the Missouri Constitution legalizing abortion up to fetal viability, which is usually around 24 weeks. Now that the amendment passed, abortion rights proponents plan to file lawsuits to strike down the state’s near-total ban.

When Missouri on Tuesday became the first state to overturn a near-total abortion ban by the vote of the people, Desiree White cried happy tears. Twenty-five years earlier, she and her husband chose to terminate a pregnancy they very much wanted after they received a diagnosis of a fatal fetal abnormality.
