"I want to knock down the economic barriers, the health care barriers, the education barriers, the kind of challenges people face every day. You're here tonight, and you're going to do everything you can in this next week, along with people in Florida, Illinois, Missouri, North Carolina, who are going to the polls. I hope you're going to the polls ."

The Democratic primary in Michigan is currently a toss-up between Hillary Clinton and Bernie Sanders.

Sanders currently leads among white voters, 54 percent to 44 percent. Clinton, meanwhile, is winning the support of women (54 percent to 43 percent), but the race is tighter among men. It is also close among white women. Sanders continues to run strong among voters under age 30 (at 82 percent support)
Those who decided on their candidate early on are going for Clinton, while the race is closer among those who made up their minds in the last week (44 percent for Clinton, 51 percent for Sanders).
