As President Joe Biden cruised through the Democratic primaries on Super Tuesday, his campaign faced a mounting challenger: a significant number of “uncommitted” votes in protest of his handling of the Israel–Hamas war.

Several Super Tuesday states included “uncommitted” options on their ballots, gathering about 254,017 votes as of Wednesday morning, according to Associated Press totals. Voters took substantial portions of the totals in North Carolina, where Biden was the sole candidate on the Democratic ballot, gathering 88,021 votes, or 12.7%, compared to the president’s 606,302 votes, or 87.3%, with 97% of the votes counted, per the AP. “Uncommitted” voters turned out in Massachusetts, too, totaling 9.4% of the vote, compared to Biden’s 82.8%, with 85% of the votes counted.
