Not really...Trump may be in terrible shape physically , but he seems more with it mentally than Biden
If you actually listen to what they say Trump is often incoherent and rambling. Trump is also very poor factually. Trump does the sales man visuals well, he gets this from TV. But that is what it is, TV.
Biden has a stutter. But he far better with the facts and knows far more detail about the facts. Biden management style is far far better.. It takes less toll out him as well, Biden could play golf for half the week.
