Eh. The dude has never been any good at public speaking. Even in the 80's when we thought he was a good speaker, it turned out he totally plagiarised his speech from some British politician.
I'm not really invested in this whole "Biden bad" campaign that is all the rage. None of the stuff is critical of the actual policies his government has produced. All the criticism is about he's old and surrounding himself with experts who are doing all the good work. Frankly, I'd be fine with that if I were a US citizen. He can be the figurehead and people who know their fields can effectively recommend the right policies. Sure beats their last president who was all "lets nuke a storm!" and other stupid stuff.
Should the USA have better options? Yes. Absolutely. Can their political system cope with someone actually good? I don't think so. Even the "good" presidents I have seen in my lifetime have ultimately been disappointing once in the oval office.
