ONE STEP AHEAD OF THE JAILER MAN:

Nearly half, 49 percent, of respondents in Michigan say they will definitely vote to replace Trump and another 16 percent say they will consider voting for someone else. Only 31 percent said they will definitely vote to re-elect Trump.

Self-described independent voters are driving down Trump's numbers. Among independents, 44 percent say they will definitely vote for someone else and 27 percent say they will consider backing another candidate, while only 18 percent say they would definitely vote to re-elect.

Meanwhile, 57 percent of women say they will vote for someone else and 17 percent say they will consider another candidate, compared to 41 percent of men who say they will vote for someone else and 14 percent who say they will consider someone else.

And while 67 percent of Republican voters said they would vote to re-elect Trump, that is well below the 80 percent of Republicans who believe he is doing a good or excellent job as president. Seventy-four percent of Republican men say they will definitely vote to re-elect Trump, but only 59 percent of Republican women agree.
