When you compare Biden to Trump vs. the effects on the Palestinians, were Trump president again, he would not just help the Israelis exterminate the Palestinians, but encourage them to do so quickly- as he’s already told Bibi to “finish it”. So your dichotomy is more than a bit disingenuous .
A lot of retrospective handwringing forgets this, or the vile comments that came out during Bill’s multiple sexual assault allegations.
Hillary was not the right candidate to fight Trump, Jeb Bush more likely. After Obama, returning to an establishment candidate was a mistake, and I don’t care if “it’s her turn” after stepping aside in 2008. Politics has real consequences for people who don’t vacation in the Hamptons.
