BEDFORD, Pennsylvania — The recent emergence of an “Uncommitted Vote” movement ahead of next month’s Democratic presidential primary, along with the surprisingly strong support for Robert F. Kennedy Jr.’s independent run for president, has experts wondering how that plays out for President Joe Biden here in November.

Earlier this week, the Democratic Socialists of America announced they were urging Pennsylvania Democratic voters to write in “uncommitted” on their primary ballots as a means to protest Biden’s handling of the war in Gaza.
