You are not the first to make that suggestion. I wish we could find real proof, but I wonder if that would matter to the crazed true believer Lefties.
I first noticed it in his nomination acceptance speech.
I replayed it for my wife and showed here some recent photo’s. She agreed it was not Joe. Delivery of the speech was perfect and it was a long speech.
Recently I viewed the one at the UN. Same impression. Perfect delivery of a long speech and no where did he slip off into the ditch.
It was NOT JOE.
There are photos out there (don’t recall where I saw them) of Slo Joe getting his shots, and in the more recent photo his arm is considerably hairier than in the other.
Though that can also be blamed on anti-seizure medicine he may be taking.
