Another thing, look at some of the recent videos, like the one where he's going up the stairs to the fake AF1. He has more pep in his step than the much younger guy who was carrying his bags! (Incidentally, he has NEVER flown on AF1, at least not as the alleged POTUS)
The masks make it very, very easy to hide your identity.
There's also the issue of the CGI presser that was blatantly fake.
Can't wait to see what he's going to do about Putin's challenge to a debate!
