Funding from groups on both sides of the Amendment 3 debate has poured into advertising and voter outreach operations in the lead-up to November's vote. The ballot put before Missouri voters includes a proposed constitutional amendment that would remove the reproductive healthcare rights — abortion access up to fetal viability among them — established by voter-approved Amendment Three in November 2024, while separately setting out provisions on abortion in cases of rape, incest, medical emergencies, and fetal anomalies, all under a twelve-week gestational threshold, alongside measures permitting legislative oversight of abortion, requiring parental consent for minors seeking the procedure, and barring gender transition treatments for minors; casting a "yes" vote would have the effect of overturning what voters endorsed at the polls in November 2024.
A further appeal by the attorneys would place the matter before the Missouri Supreme Court. Under the proposed measure, terminations would be permitted during the first 12 weeks in documented cases of incest, sexual assault, or a threat to the patient's health. The measure's provisions extend to restrictions on certain medical procedures performed on minors relating to gender transition. Legislation enacted by Missouri's General Assembly in 2023 prohibits the practice, though a provision within that statute is set to expire in 2027.
Financial disclosures show that Her Health, Her Future, a group backing Amendment 3, has gathered over $5 million in funding, with the bulk of those contributions coming from donors within the state. The committee, established the previous month, directed its available funds entirely toward reaching voters through outreach efforts, a representative noted.
Amanda Sanders, speaking on behalf of Her Health, Her Future, stated that the group's outreach effort aimed to put factual information about Amendment 3 in front of every voter across Missouri. Sanders asserted that the organisation draws all its funding from within Missouri, yet went on to cast doubt on that very position by pointing out that genuinely local financial backing would be traceable in the actual origin of the contributions.
The group opposing Amendment 3, Stop the Ban, had collected over $27 million by the latest financial disclosure deadline, putting its fundraising total within roughly $3 million of the approximately $30 million that backers of the 2024 abortion ballot measure raised in support of that campaign. Three groups operating at the national level — the American Civil Liberties Union, Planned Parenthood, and The Fairness Project — rank among the largest financial backers of the campaign. Filings tied to campaign finance show contributions flowing in from individual residents across Missouri.
Stop the Ban, through a written statement attributed to Tom Bastian, described residents stretching from Cape Girardeau to Maryville as broadly aligned against Amendment 3, with the organisation arguing that the measure would leave open a path for legislators to restore an abortion ban — an outcome the group frames as running counter to what Missouri voters have already decided. Bastian noted that residents from more than 75 Missouri counties had contributed financially or given their time to the campaign, and the quoted statement expressed collective appreciation toward those participating in efforts to vote against Amendment 3, halt the abortion measure, and uphold the outcome the public had chosen.
Passage of Amendment 3 would undo the abortion access provisions that Missouri voters approved through a 2024 ballot initiative. The ballot question is set to go before the public that coming November. Unrestricted early voting is set to get underway in the coming week.
