@ehBeth,
I think Obama is aware his very name sends some people into orbit, and he may be smart to still keep being presidential in this continually troubled world scene, but that's a view of mine and not his, far as I know; Hillary may have discouraged him re campaigning, but I don't know that either.
Biden, though, a lot of people like him, or at least don't hate him. Nobody's perfect, but I prefer him to Hillary myself, even though he is older. On the other hand, she's growing on me, but I'm still on the wary side over this and that. I've no idea if he and she are pals at all.
I'm beyond wary about Trump L'oeil, speaking of visual illusion, or illusion in general.
