DEARBORN, Michigan — President Joe Biden easily won Michigan’s Democratic primary, but a grassroots campaign aimed at sending him a message over his response to the Israel–Hamas war surpassed its goal, showcasing the growing dissatisfaction the president faces within his own party.

The Associated Press called the race for Biden shortly after all the polls closed at 9 p.m. But while the incumbent president garnered 81% of the vote in an uncompetitive race, another 13% of the voters marked themselves “uncommitted.”
