My father read and re-read Aesop's Fables to me quite often at night while we were going to sleep. Even today I can recite many verbatim. As I lay in bed, my young mind would conjure up pictures of the characters in the fable.
The fox and the grapes was classically simple: losers are bitter and cast blame outward rather than inward. McCain and Graham, two of the three GOP campaign trio [sans Lieberman], say Obama is 'off to a bad start,' as CNN puts it.
That other fable comes to mind regarding the senators: The Ass and His Masters.
