Wonder what the problem is? Lately he has looked more aged and haggard. So maybe he has a medical condition...? very possible at 78 yrs old...
What ever, he is aged out as is the Biden...and Liz Warren is 70 now, and no spring chicken any longer... these election campaigns last way too long !!!
And here I was thinking how good he looks. I knew him personally since 1966, and had many friends (and social events) in common, but haven't seen him since moving away from the area 20 yrs ago.
