Not the only factor, of course, but social media slop has played an underestimated role persuading Jewish-American boomers and Gen Xers that the Democratic party is on the verge of an antisemitic, or even anti-Zionist, "takeover."
You can't be a well-informed, discerning observer f US politics and maintain that the party of Chuck Schumer and Hakeem Jeffries is on the slippery slope to pogroms.
You can't live in reality and think that AOC has it in for Jews.
There's been a real shift at the Dem median but it's a shift favoring stronger condemnations of Israeli war crimes and settler expansion, and exerting real leverage on Netanyahu's government, rather than giving them the de facto blank check Biden did.
If *that's* your idea of an antisemitic takeover you're so far from reality you should seek treatment.
Jews are washed imo - total collapse in their once vaunted ability to interface with the American political system because their donor decision making is driven by emotional reactions to slop
