Michigan Voters Reject Constitution Revision

Nearly half of Michigan’s likely voters said they would vote no on Proposal 1, a measure to rewrite the state constitution.

The WDIV and Detroit News commissioned a survey by The Glengariff Group, Inc. to gauge public opinion ahead of the November 2026 general election. The pollsters conducted live-operator telephone interviews with 600 residents between October 19 and October 22, 2026. The margin of error for the study is plus or minus 4.0 percentage points at a 95% confidence level. The sample included 15.0% of respondents reached via landline and 85.0% reached via cellphone.

The survey asked participants a specific question regarding a constitutional convention. Every sixteen years, Michigan law requires voters to consider holding such a body to draft a general revision of the state constitution. The poll question asked if voters would approve convening a convention of elected delegates in 2027 to draft that revision. The resulting breakdown of answers was 34.4% in favor, 48.5% against, 15.9% undecided, and 1.2% who refused to answer.

The data indicates a clear preference among respondents to keep the current document rather than initiate a full rewrite. The gap between those supporting the convention and those opposing it stands at 14.1 percentage points. This margin exceeds the poll's stated margin of error, suggesting the opposition is not a statistical anomaly. The undecided group accounts for a substantial portion of the electorate, nearly one in six individuals.

Voters will cast their ballots on Proposal 1 during the November 2026 general election. The measure appears on the ballot as a direct question to the electorate. If approved, a group of elected delegates would begin the drafting process in 2027. The final revised document would then return to the public for a second vote on approval or rejection.
