Neither candidate was ever going to push back against Israel's genocide of Palestinians.
While it was very disappointing the Democrats weren't exerting significant pressure against Israel, and Kamala gave no indication she'd act any different, it was delusional to believe Trump was going to be any different. He was very clear that he supported Israel as well, and he went as far as to claim he'd support Netanyahu even more strongly than Biden. Sure, he sabre-rattled a bit about wanting the war in Gaza to end before he took office, but he also indicated he'd support residual IDF actions (i.e., continued killings of Palestinians) within Gaza afterward.
There was never a candidate who was going to push back against Israel, no matter how much you or I would have liked for there to have been one.
