Research draft. We gathered this from official sources on October 27, 2026: election offices, state laws and court records, each linked to its source. Separate reviewers checked a random sample of 48 facts from the ballot-measure research against the cited sources and found no errors. The rest hasn't been reviewed fact by fact yet, so check the linked source before relying on anything here.

§3Notes on the research

What the research couldn’t find or confirm, in its own plain words. Nothing is left out silently.

  • Amendments 1, 2, 4 and 5 were statewide measures at the August 4, 2026 primary election, not on the November 3 ballot, so they are not listed here.
  • We could not read the official August 4, 2026 results: the Secretary of State's results site (https://enr.sos.mo.gov/) answered with a Cloudflare block, again to a single request at a slower pace on 2026-10-27, and the Secretary of State's results page links the 2026 primary results only to that site. This matters for Amendment 6: August's Amendment 4 would have required constitutional amendments proposed by initiative to win a majority in each congressional district. News reports (not an official source) say Amendment 4 was rejected by about 80 to 20 percent; the threshold here assumes the statewide-majority rule in Mo. Const. art. XII, § 2(b). A reviewer should confirm the Amendment 4 result from the official canvass.
  • Missouri's official ballot titles are full ballot questions, so no short title is given for any measure.
  • The Secretary of State's page names the referred act House Bill No. 1 (2025 Second Extraordinary Session) in Proposition A's ballot title but (2025 Extraordinary Session) in its fair ballot language; we used the ballot title's wording.
  • The initiative petition for Amendment 6, the referendum petition for Proposition A and the certificates with the attached court opinions are scanned images. We read them with text recognition, which left a few words unreadable; none of the points we relied on fell in those spots.
