The answer is simple; the overturning of Roe v Wade. That is what motivated the Dems in Michigan.
The Demorats supported an indepdent candidate in the ND House race, Cara Mund-the first woman from North Dakota to win the Miss America contest and Harvard Law School graduate to boot.
Ran as a pro-abortion candidate. She lost to the Republican incumbent, Kelly Armstrong.
The election was a nail biter-Kelly 62.%, Mund 37.6%
So Michigan before and after the recent decision to over turn Roe v Wade was pro-abortion.
