"The more we do polling, the more the numbers look the same to me," Glengariff founder Richard Czuba told the newspaper, noting the continued Democratic advantage in the state. He added that Trump could still win the state, depending on the Democratic nominee.

Trump’s 10,704-vote victory in Michigan in 2016 was the slimmest margin of the three pivotal states — Pennsylvania, Michigan and Wisconsin — that swept him into the White House.

The new poll was conducted among 600 likely Michigan voters between Jan. 3 and Jan. 7. It has a 4-point margin of error.
