Biden isn’t quite as bad as the soundbites make him seem, but he is slowing down (physically and mentally) in his old age and was just generally an extremely uninspiring candidate. Trump, if anything is worse than you portray. He’s way more senile than Biden, in addition to the blatant corruption, rulebreaking, childishness, and being horrifically and openly racist and sexist. Literally no decent and reasonable person who is paying the slightest attention to what he says and does would think he is remotely qualified for any position of authority. The fact that he is polling roughly evenly with an extremely qualified and intelligent person like Kamala Harris is indeed an absolute clownshow.
