Proposal 26-1: what your vote means
Constitutional convention. On every Michigan ballot. Official sources checked October 21, 2026.
Proposal 26-1 · Constitutionally required question (every 16 years)
Constitutional convention
Shall a convention of elected delegates be convened in 2027 to draft a general revision of the State Constitution for presentation to the state’s voters for their approval or rejection?
Ballot wording as certified by the Michigan Bureau of Elections.
A YES vote means:
A convention of 148 elected delegates would meet starting in 2027 to draft a general revision of the Michigan Constitution, which voters would then approve or reject.
A NO vote means:
No constitutional convention would be held; the question returns to the ballot in 16 years.
What it would change
- Who is affected: all Michigan residents; delegates would be elected from each of the 38 Senate and 110 House districts.
- Next step: any proposed constitution must go to voters within 90 days after the convention adjourns.
- Timing (Senate Fiscal Agency): delegates would likely be elected in 2027 and convene in Lansing in October 2027.
- Fiscal impact: The Senate Fiscal Agency says costs are difficult to estimate and offers three approaches: about $10.2 million total (1961 costs inflated), about $1.8 million per month, or about $3.9 million per month; elections not held on regular dates could add about $20.3 million each.
