He lived in an "ambulatory care home" in Georgetown.
I was sorry to see that none of his relatives had room for him.
Kind of like King Lear.
I'm not surprised, I remember reading an article (a sort of where are they now type piece) about him a few years ago.
The impression I got was that he had become very bitter with pretty much everybody and disallusioned.
The way it was implied was that he had pretty much turned on everyone, democrats, republicans, independents, friends, family, etc.
The mystery was what happened that made him so bitter against everyone.
