RON’S COMMENT: Michigan proved to be a critical swing state in 2016 that Trump won by a tiny margin. This poll shows these four Democrats now beating him, with Biden doing best. Of course, early polls in 2016 showed Hillary Clinton beating Trump in Michigan, too.
Looking at the Democratic governor of Michigan, Gretchen Whitmer, her job rating is 43% approve/45% disapprove and her personal favorable rating is 46%. Whitmer was elected last November with 53% of the vote.
