US President Joe Biden largely won the Democratic primary in Michigan on Tuesday. But its success was marred by more than 100,000 “uncommitted” votes, the equivalent in the United States of the blank vote.

A collective of activists had called on voters to retain this option to sanction Joe Biden's policy in the Middle East, and push him to work for a ceasefire in Gaza. “President Biden is financing the bombs that fall on relatives of families living right here in Michigan, people who voted for him and who feel completely betrayed,” a campaign official said.
