The Demosucks are banking on the "left" voting for The Cop, simply on the merit that she's not the Orange Man. They probably will lose a significant % of those votes from the people who are actual human beings with a moral compass, that recognize Israel is being assisted by the US to commit multiple genocides. But it's very likely their internal polls show they'll gain just as much votes from the anti-Trump crowd, so they don't care.

Besides, you can't be a US politician going for office without the backing of the Israel lobby.

Honestly though, on the bright side, if the US keeps backing Israel so hard, Israel will very likely self-destruct and will take down the US with it. They are both already getting more and more isolated diplomatically.
