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.
The questions were absolute dogshit as well.
Imagine outsourcing your political discourse to CNN who will not call out any innacurate statements and inject commercials into the debate.
Pretty much every facet of this farce shows that the USA is a fucking joke and gives all the power to 'news outlets' like cnn.
Part of this is also that the two parties have to agree to the terms of the debate, so you won't end up with anything actually rigorous or interesting. Still, you'd think if this was the end of american "democracy" that the moderators would maybe once have tried to get someone to actually answer a question.
