“I was proud today to walk in, and pull a Democratic ballot, and vote ‘uncommited,’” Tlaib said in a video message on Tuesday. “President Biden is not listening to us. This is the way we can use our democracy to say: listen. Listen to Michigan.”

“President Biden has funded the bombs falling on the family members of people right here in Michigan,” Elabed said in a statement on Monday. “Thousands of Michigan Democrats who voted for Biden in 2020 now feel completely betrayed.”

It remains unclear how many of the “uncommitted” voters will continue to withhold their support in the general election, but organizers have argued that it’s on Biden to earn their support — and they say it won’t be their fault if Biden ends up losing Michigan to former President Donald Trump in the general election.

Ahead of the Tuesday primary, officials with the Biden campaign had pointed out that around 20,000 voters have opted to select “uncommitted” in recent presidential primary elections — though the circumstances have varied.

“Uncommitted” accounted for less than 2% of the vote in recent competitive primaries, including 19,106 uncommitted voters in 2020, and 21,601 in 2016.

Four years earlier, when Obama did not appear on the ballot, many of his supporters cast uncommitted votes over his opponent Hillary Clinton, leading to 238,168 votes that accounted for roughly 40% of the electorate.
