Michigan voters are poised to approve a ballot proposal to legalize recreational marijuana in the state this November, according to a WDIV/Detroit News poll.

Ballot proposal: Legalization of recreational marijuana in Michigan

By a margin of 56.2 percent-38.0 percent, Michigan voters support legalizing recreational marijuana. Only 5.8 percent of voters remain undecided. These numbers have remained consistent for the past two years.   

Only voters over the age of 65 are sharply opposed to the marijuana proposal.

The chart below compares the proposal’s support by party affiliation. Unlike other proposals, there is no sharp opposition by party affiliation.  Republicans and Independents are split on the proposal, while Democratic voters strongly support it.  

Party Affiliation                      Support           Oppose

Strong Democratic                  71.1 percent                24.3 percent

Lean Democratic                     70.3 percent                17.0 percent

Independent                            47.1 percent                45.5 percent

Lean Republican                     49.4 percent                49.4 percent

Strong Republican                  41.3 percent                52.5 percent


The more statistically significant demographic appears to be age.

Age                                         Support           Oppose

18-29                                       79.2 percent                19.5 percent                           

30-39                                       71.6 percent                21.5 percent

40-49                                       57.0 percent                39.0 percent

50-64                                       52.4 percent                40.6 percent

65+                                          37.1 percent               55.7 percent

Ballot proposal on redistricting

By a margin of 37.8 percent-31.4 percent, a plurality of Michigan voters narrowly support a constitutional amendment that would create an Independent Redistricting Commission to handle redrawing legislative and congressional district boundaries. 30.8 percent of voters remain undecided.  

There are stark differences on the redistricting proposal by party affiliation. Strong Republican voters are sharply opposed to the constitutional amendment.  

Leaning Republican and Independent voters are split, with Democratic voters in support of the proposal

But this constitutional amendment is NOT in the upper fifties as is historically required at the start of a campaign to be positioned for passage.
