The most fitting analogy: Hillary is a Monty Python character.
I finally get it. After all these months of watching Hillary come back and come back and come back, even though there was no realistic hope of winning, I finally realized who she reminds me of.
Ever see Month Python and the Holy Grail? She's the Black Knight!
If you haven't seen it, the hero gets into a sword fight with the Black Knight, who first gets his arm cut off, but continues to fight. The his leg goes, and he hops around, daring the other knight to attack. Then his other arm and leg are cut off, and he lies there, calling the other knight a coward for running away.
Of all the possible images and analogies, this is Hillary Clinton.
