Constitutional Amendment 4: Initiative Petition Approval by Congressional District Majority
Missouri
My vote power
Above average
Election date
August 4, 2026
How do we calculate my vote power?
What goes into the rating for ballot measures: Representation: how much weight one vote carries here compared with a statewide vote — the smaller the district, the more each vote counts. You have more power in ballot measures because you vote directly on the policy.
Representation: Average · 50 out of 100
This district covers a large share of its state, so each vote carries about average weight — like a vote in a statewide race. About 6,191,814 people live here.
Show the representation math
score = 50 + 50 × ln(state population ÷ this district's) ÷ ln(50,000) = 50 + 50 × ln(6,191,814 ÷ 6,191,814) ÷ ln(50,000) = 50, measured against a statewide vote in MO (grades: 66+ high, 55+ above average, 33+ average, otherwise low; a statewide race is the 50 baseline)
Average representation + a direct vote on the policy → My vote power: Above average.
Ballot Measure
Supports: Election Integrity
This amendment would require citizen-proposed constitutional amendments to win a majority in every Missouri congressional district, instead of one statewide majority. Voters would receive the full text. It would also ban foreign-national funding of ballot campaigns, create crimes for petition fraud, and require public hearings before initiatives reach the ballot.

A YES vote means
All listed rules would enter the Constitution. One congressional district could block an amendment that wins statewide.
A NO vote means
Current statewide-majority approval would remain. The Constitution would not add the other campaign, petition, hearing, or ballot-text rules.
