A recent poll of over 900 likely Missouri voters shows a tight race for Amendment 3. A ‘yes’ vote would remove abortion rights from the state constitution and ban gender transition procedures for minors.[1]
Currently, 43 percent of voters support the amendment. Another 44 percent oppose the measure, leaving 13 percent undecided.
The measure would remove abortion rights from the state constitution and ban gender transition procedures for minors.
The numbers represent a drop in support since the start of the year. A previous poll in February 2026 showed a seven-point lead for the amendment.
The data reveals shifting demographics among state voters. Amendment 3 is polling well among non-white voters and those aged 30 to 44.
However, the measure is underperforming with elderly and low-income earners.
St. Louis University and YouGov conducted the survey. The questionnaire was lengthy and covered multiple political figures and upcoming elections.
The Amendment 3 question appeared later in the survey. Respondents may have experienced fatigue by the time they reached the topic.
Missourians will vote on this issue on November 3. How will you vote?
