ddfred: I believe 100 percent that someone impersonates him in a mask. Saw a Fake Book video by a former CIA person discussing the masks. I was onto it well before I saw the video. At certain times, Biden's face was much fuller, shinier (as though he had had a face lift), and there were no lines or wrinkles. He looked like a figure in a wax museum. It was obvious it was not him.
Another possibility is that he looked so terrible, say, due to Bell's Palsy, that he himself wore the mask.
One thing is certain. He drags his leg somewhat when he walks, which strongly suggests he has had one or more TIA's. I found some of the shots of him at Rehobeth Beach to be suspect. Given his gait, I very much doubt it was Joe Biden himself walking the German Shepherd along the beach.
