The leads for Warren and Harris over Trump were 4 and 3 percentage points respectively, falling within the survey's margin of error of 4 percentage points.

Just more than one-third of likely Michigan voters — 36 percent — said they would vote to reelect Trump, while 51 percent said they intended to vote for someone else.

Pollster Richard Czuba pointed to Democratic apathy for Trump's win in the state in 2016 — the first Republican victory there since 1988. Trump won the state by 10,704 votes in 2016.

“What we saw in Michigan in 2016 wasn’t this giant surge of Trump voters — it was an absolute apathy on behalf of independents and leaning Democrats to vote,” Czuba told The Detroit News. “We’re seeing the exact opposite heading into 2020,” he said.

The poll of 600 likely Michigan voters was conducted from May 28 to 30.
