Bipartisan opposition from labor unions, business groups, education advocates, and figures across party lines has coalesced against Michigan's automatic Proposal 1, which asks voters on November 3, 2026, whether to convene a constitutional convention for general revision. This builds on repeated historical rejections in 1978, 1994, and 2010 by wide margins, with organized campaigns highlighting risks to established provisions on education, labor, and other areas through delegate-driven processes. Recent polls show plurality yes support but substantial undecideds, yet trader consensus at 96.1% No reflects the entrenched pattern of voter caution and active resistance. Late developments such as major shifts in turnout, surprise endorsements, or unforeseen campaign developments could still narrow the outcome before election day.
