Michigan Democrats and Republicans wrap up their presidential primaries today

Both President Biden and former President Donald Trump are vying for their party's delegates in Michigan today. Neither contest is expected to be competitive — even though the state will be pivotal in the general election come November.

Trump, who is coming off a big win in South Carolina, has one remaining major challenger. Former U.N. Ambassador Nikki Haley has vowed to stay in the race for the GOP nomination until at least Super Tuesday on March 5 — despite losing by almost 20 percentage points in her home state.

Phillips got less than 2% of the vote in South Carolina's Democratic primary on Feb. 3, which is the last time he participated in an election contest.
