“Before this conflict I always thought Israel was a consistent ally that we would always support, and I never had any issues,” she told the BBC. “But I think the American people have been forced to consider the historical context in the situation.”

One possible reason for the divide is that young Democrats, particularly progressives, are also more likely to connect the cause of Palestinian statehood to the fights for social justice playing out in the US.

“A lot of the organisations that I’m present in have made strong connections to what the Palestinians experience, and want to continue to uplift their struggle,” said Michael Abramson, the 25-year-old policy director of Young Democrats of Maricopa County in Arizona.

Mr Abramson organises in a key Arizona county for Democrats. He said he was confident the youth would turn out in Arizona for other candidates and ballot measures – such as abortion – but he said he was unsure whether he and others would vote for the Democratic nominee, whom he called “the lesser of two evils”.

Democrats relied on young voter turnout to propel them to victory in the 2020 presidential election and the 2022 midterms. The Democratic apparatus typically pours millions of dollars into youth outreach and engagement to shore up support.
