I grew up 30 minutes outside of Dearborn, Michigan, a city with the largest Arab-American population in the country, and one that is largely responsible for the protest vote by Democratic primary voters against President Joe Biden this week. Their complaint against him primarily revolves around his continued support for Israel in the Gaza conflict, but they managed to convince large swathes of young voters in Ann Arbor to vent their frustration against the Democratic ticket as well. In total, more than 100,000 Michigan Democrats voted “uncommitted” instead of for Biden, and in the parts of the state where the Muslim population is highest — Dearborn, Dearborn Heights, and Hamtramck — Biden flat out lost.

Biden still easily clinched the Democratic nomination in the state, but the fact that so many of his own party’s voters mobilized against him should be setting off alarm bells in his campaign. Indeed, it begs the question of what the results might have looked like had Biden been forced to face some real competition.
