What Is Amendment 4?

Amendment 4 would change how Missouri passes ballot measures from a simple majority of votes statewide to requiring a measure to win a majority of votes in all eight of Missouri's congressional districts. Under this change, a single congressional district — representing as few as 5% of the state's voters — could defeat a measure even if a majority of all Missourians supported it.

What Voting NO Means

Voting 'No' on Amendment 4 on August 4, 2026 means keeping Missouri's existing standard for passing ballot initiatives, where a statewide simple majority of voters is sufficient to approve a citizen-led constitutional amendment. Missouri voters have used this initiative process for more than a century.

Get Involved

The campaign invites Missourians to join the effort, stay informed about progress, and find ways to get involved before the August 4, 2026 election. The committee works in coordination with Missourians for Fair Governance and other allied organizations.
