@Strandjunker No, its not that simple.
Just because a candidate wins a popularity contest does not mean they will be capable of making the timely and correct decisions at critical moments at 4am Eastern time when something happens in Ukraine at 11 am. We don’t have a way of knowing that. Only the team that works with the President on a daily basis can make a guess based on CURRENT performance.
As a country, we’ve been mostly lucky picking Presidents so far with some exceptions.

@bouriquet @Strandjunker yes indeed, the team working with Biden knows what's wrong with him. They should come clean about what it is, instead of saying "oh nothing, he's fine" and making wishes that won't come true.
