No real answers or policy proposals, blaming every problem on migrants (while Biden's policy on the border is largely a continuation of Trump's), just a bunch of bullshit "everything was great, now everything sucks, but I will make it great again". I honestly cringed at Trump more, Biden's ramblings at least were funny.
I can't imagine anyone who's undecided at this point listen to this and say "This guy will make things right". Trump's entire objective is to let Biden stumble and fall and then cruise to presidency, but he makes every effort imaginable to prevent himself from it. No zingers or clever retorts against a literal corpse (aside from maybe one "I don't know what he said and he isn't either"), just and abysmal performance. Honestly, even someone like Ramaswami would've dogwalked Biden.
If anyone is capable of losing to Biden at this point, it's Trump.
Also during Trump's presidency he did many things which hurt Palestinians and helped Israel, such as the Abraham Accords and moving the US embassy from Tel Aviv to Jerusalem. He also cut funding to Palestinian aid groups, stopped funding to UNRWA. There's also speculation that his assassination of Qassem Soleimani was on behalf of Israel.
