Both Donald Trump and Joe Biden won their primaries in Michigan yesterday, but the vote revealed vulnerabilities for Joe Biden that could come back to haunt him in November.

Why Michigan mattered: It was Donald Trump’s victory over Hillary Clinton in Michigan that sealed the 2016 election, and Joe Biden’s triumph over Trump there and in other Upper Midwestern states in 2020 that decided the election. In all probability, it will play a decisive role this November

Michigan is also home to the largest Arab-American population in the United States. After a concerted campaign in protest of the Biden administration’s policy toward Israel and Gaza, 13 percent of Democratic primary voters chose “uncommitted” last night. In Dearborn and Hamtramck, two of the Michigan cities with the highest concentrations of Arab Americans, “uncommitted” won 56 and 61 percent of the Democratic vote respectively. Significant portions of Michigan’s college towns also voted uncommitted in protest, foreshadowing how many young, progressive voters are angry about American support for Israel.

GOP voters once again rejected Nikki Haley in favor of Donald Trump. Haley lost for a fifth time against the former president, winning 27% of the vote against Trump’s 68%. She has vowed to stay in the race through Super Tuesday, where the lion's share of the delegates are up for grabs.
