Most likely it's a some sort of Parkinson's freeze-up
or extreme dementia episode. I have seen this sort of thing
personally with family members (father and
father in-law.)
Maybe with time and medication the doctors can
pull Biden out of it.
Do they really want him alive?
He would be a witness—albeit a senile one—to their blatant lying and forgery.
You may be correct—but I think they would finish him off if that happened.
Otherwise he might recover and insist he is still running for a second term.
As they said in “Breaking Bad”....
No half measures.
