I can't recall in my lifetime any presidential candidate that has had as hectic a pace and schedule as Trump. He would have to be in pretty good physical shape to carry it off.
It’s a cinch that uncle Joe can’t keep up that kind of pace. That said, Biden can’t draw the crowd and even with Obama stumping for him and Harris out campaigning to people standing at the polls (quite illegal), the three of them haven’t come close to what D. Trump does.
