But the rub is: since February or March it's been obvious that almost certainly neither Obama nor Clinton could wrap up an "insurmountable victory" with pledged delegates alone. Therefore, the historical analogies you are referring to are simply inappropriate here. I think the appropriate analogy is Gary Hart's capitulation to Walter Mondale. Hart waited until Mondale passed the "magic number" with pledges from superdelegates.

Btw, congrats on surviving the primary season. Clinton is (mostly) history. I can go back to reading The Dish with my usual enthusiasm.
