It's not that he's 81 Roma. Buffett is 93 can you compare them? It's simply that he has lost it. Some people remain sharp till they die. Others lose it much earlier. Biden is clearly in the 2nd category. As for whether he is full-on senile or not, how would I know? How do you know? Because his cronies tell you so? I mean if you believe Kamaliar and her bunch Biden is sharper than the sharpies and smarter than the smarties. Not too long ago they were telling the world he has a photographic memory. So, no I can't trust any of that and based on what I have seen I have every reason to suspect his senility quotient is pretty damn high.
