My position is that this will cost Obama the Democratic nomination. Neither Clinton nor Obama will have 2025 delegates. The super delegates will decide and go with Clinton to win the general election after she wins decisively in the majority of the remaining 10 primaries.
Obama does not yet have the nomination.
Ok, fair enough.
I would respond that Muskie and Dean were felled for things they actually said or did, while Obama's problem is one of association. In addition, those both happened at the same time in the calendar year, but far earlier in the process. That was still in the Iowa-NH period, whereas most delegates have been assigned and Clinton would need to get a ridiculously high percentage of Democrats, something which does not appear to be happening following Wright. Finally, Dean was on his way out before the scream, that was just the nail in the coffin.
