Democrats overseas

What is it about Democrat former presidents and vice-presidents who feel perfectly comfortable criticizing their own country when outside the United States? Who are they appealing to and for what reason? Do they get some kind of reward for trashing their own country? A pat on the back from Europeans? Environmentalists? Socialists? Is it about money? They sell books by selling out their county?

It's like trying to entertain friends and impress strangers by revealing your family's skeletons. Respectable people don't do it but Al and Jimmy do.
