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 .
If he had more votes in the primary, then that could have been true despite the superdelegates. As it would be true for any other candidate.
But he/they didn't, and here we are moping over something that didn't happen years ago while the USSC lays the final stones in the foundation for an actual dictatorship.
