A lady friend of mine and her 16-year-old daughter went to the White House in 2013 when he was vice-president to get some sort of award. After they shook hands with Biden, he made some comment about what a cute girl she was and he was going to keep her around (all joking of course?), and grabbed her and held her to him while he shook hands with the rest of the people in the line.
They said it was the creepiest, most inappropriate thing they'd ever experienced. No one else seemed to think anything about it, because he did it all the time.
But if you get the full videos (undoctored) of his speeches and press conferences, you'll see that he's WELL into senile dementia. Can't keep a coherent thought, constantly loses his place, says the wrong thing ... it's almost like elder abuse to have him in that position. Chances that he'll make 4 years are around zero ... but that MAY be part of the plan ....
