This is starting to align again with all the people who predict Biden will still win. Once the Palestinian cause becomes politicized and turns into the same blue vs red team, once the genocide becomes a question of whether or not you're handing it to Trumpists, it is over.
The neoliberals were definitely correct in pushing the whole Ukraine war as a matter of "western values" and if the Gaza genocide becomes "we can't allow the Axis of Evil/Trump allies to dictate terms" shit then libs will support Biden even harder.
The only reason the Israel propaganda is less effective is the generational issue(gen z doesn't care about Ukraine) and maybe Israel/Zionism went too hard and too fast on the whole "right to defend itself" narrative and it is hard to back off from that.
