I don't think we will know who won the election when we going to bed on election night. It is going to be a close race. Biden would not have been my first choice because of his age, but it isn't like Trump is a whole lot younger. Biden has said some stupid things, but just the other day Trump said that it was the Spanish flu that brought World War II to an end (he was only off by 25 years, and the flu alone didn't end any wars). I know of people (including my mom) who supported Trump four years ago who have turned against him because of his handling of the pandemic. I think we would agree that it will be close. In any event, VP choices don't swing elections.
