President Joe Biden and former President Donald Trump won the Michigan primaries on Tuesday, further solidifying the all-but-certain rematch between the two men — yet early results from the state were highlighting some of their biggest political vulnerabilities ahead of the November general election. A vigorous “uncommitted” campaign organized by activists disillusioned with Biden's handling of the war in Gaza was making headway. It had already far surpassed the 10,000-vote margin by which Trump won Michigan in 2016, a goal set by organizers of this year’s protest effort. As for Trump, he has now swept the first five states on the Republican primary calendar. But there were early signs that Trump was continuing to struggle with some influential voter blocs who have favored former U.N. Ambassador Nikki Haley in previous contests. Haley’s strongest performance Tuesday night came in areas with college towns like Ann Arbor, home to the University of Michigan, and suburbs around Detroit and Grand Rapids. For Biden, the notable percentage of “uncommitted” voters could signal weakness with parts of the Democratic base in a state he can hardly afford to lose in November. Trump, meanwhile, has underperformed with suburban voters and people with college degrees, and faces a faction within his own party that believes he broke the law in one or more of the criminal cases against him. Michigan has the largest concentration of Arab Americans in the nation. More than 310,000 residents are of Middle Eastern or North African ancestry. Nearly half of the Detroit suburb of Dearborn’s roughly 110,000 residents claim Arab ancestry.
