Actually, I can understand his strategy. As President of the United States, he needs to put forth the image of health, vitality, and strength. This assures the country and the world that he is fine and well capable of continuing his ability to run this country. For national security purposes, it is a necessary "white lie" that he has to tell.
Oh, would that that were true...
It's one thing to put on the brave face and tell America, "Hey, it was a struggle for a little while, but I'm fine now," but it's completely something else to say, "Hey, this Covid thing is not all that bad. I had it and now I'm over it. Don't even worry about getting it. We're doing a great job!"
It's one thing to get seriously ill and pretend that everything is all right just so the public doesn't panic. But when you do that, and the VP, Pence, who SHOULD be under quarantine, staying isolated, and preparing to fulfill his duties as VP should the President become unable to function as President, decides to continue on with his life of socializing "normally." How irresponsible. It's as if the administration believes if they just say "everything is fine" enough times, then they really don't have to do anything. It's as if they are actually believing their own B.S.
