Michigan Voters to Decide on Constitutional Convention in November

Michigan voters will decide on November 3 whether to trigger the first constitutional convention in over 65 years via Proposal 1. If approved, 148 elected delegates would convene in Lansing by mid-2027 to propose a general revision of the 1963 state constitution. Any resulting changes would require final voter approval in a subsequent statewide election.

Gretchen Whitmer and a bipartisan coalition, including the nonprofit Voters Not Politicians, oppose the measure. They argue the convention is a "Trojan horse" designed to roll back fundamental rights, specifically the 2022 abortion access amendment. State Representative Jay DeBoyer previously suggested a convention could be a method to repeal those reproductive protections, though he later attempted to walk back the remark.

Supporters, including Republican consultant Dennis Lennox and State Senator Jonathan Lindsey, argue the current government is unaffordable and that a new constitution is necessary to lower taxes and restore local control over zoning for data centers and solar farms. A WDIV/Detroit News poll shows 47% support and 31% opposition for the proposal.
