Hmm. I feel sure the Joe Biden who didn't really get elected had had some cosmetic surgery this year, and Trump remarked on his facelift at a rally, I think. Just in passing, didn't dwell on it. Commonly people do that to look younger, but you have to have something to work with and it has to be something that would heal fast. The earlobe which has vexed many is still there when seen in profile but now the jawline is a little thicker and obscures it in the front view. I guess a guy could put fillers in his jaw to look younger and stronger. His skin had red blotches for about a month and his nose is a little shorter and straighter, laser smoothing and a nip off the tip. This is the Occam's razor view. Of course he could be a double, but if he is taking Joe's place, then he is missing from his own place in the world. That has to be explained.
