Joe Biden cannot remember what he said or did an hour ago, much less a year or a month....
He has bonafide Dementia. What exact stage he is in I have not seen enough of him to say, but I would guess he is around stage 3 and moving toward 4..
I kept track of my dad's progression with a chart that described in great deal the things that each stage of getting progressively worse will bring and checkmarked them as I saw them.
As frail as this putz is, he is not going to be President for a whole lotlonger unless of course we are doing replicas of Weekend at Bernies. Don;t put anything past the NAzi party in the white house..
