President Joe Biden won the Michigan Democratic primary on Tuesday, but over 100,000 voters cast their ballots for “uncommitted” in an organized campaign protesting U.S. support for Israel’s assault on Gaza. The major battleground state is home to one of the largest Arab American populations in the country, but the movement to vote “uncommitted” is now expected to spread to other states, including Minnesota and Washington. “I’ve rarely seen such an organic and authentic movement come together,” says former Democratic congressmember from Michigan Andy Levin. “We really need actual change in policy, and I think we sent that message strongly last night.” President of the Arab American Institute James Zogby says that Democratic voters need a reason to come out to the polls. “We gave them a reason with ‘uncommitted.’ Joe Biden’s got to give them a reason in November,” says Zogby. “There is genocide unfolding. People want it to end. The president either is going to have to act decisively to end it, or it’s going to have an impact in November.”
