Sure. Just take a look at all the nascent support for Israel on American's college campuses and from illustrious democrats such as Rashida Tlaib and Ilhan Omar. Good luck!

I have taken a look at that. Unlike you, though, I've looked at things other than what the very most progressive parts of the hardcore left are saying on just that one issue. Dissatisfaction among Jews with the position of the most leftward part of the Democratic coalition isn't going to get them to move to the party that promotes the idea of the US as a Christian nation. No coalition that makes up half the country is going to be a perfect fit for any minority group like the Jews - and the Democrats are a much better fit than the Republicans. We might be very upset by what the far far left believes about Israel, but we're not going to leave the Democrats for the party of rural nativists promoting a hardcore Christian view of culture and government. Particularly not while the far far left doesn't set Democratic foreign policy.
