Clinton's claims wrt the popular vote are extremely disingenuous, and totally beside the point, anyway. First off, it's impossible to say what the popular vote would be if the Caucus states had primaries instead of caucuses. It's impossible to tell just how many repubs heeded Rush's call and voted for Hillary in open primaries, too.
The only metric that matters is delegates, period. That was agreed upon long before anybody started campaigning. And the exclusion of the MI and FL delegates was also known before they ever voted in their improper primaries. They were joke votes, meaningless, and everybody knew it.
And all of this talk about Obama's "blackness" is a joke, as well. The only things "black" about Obama are the color of his skin and his sympathy for the american black community. His father was Kenyan, a whole different culture, and separated form Obama's white mother when Obama was 2. He lived in Indonesia a few years as a child, attended a school for foreigners. He was raised by his white family in Hawaii. He attended Columbia and Harvard Law, and was president of the Harvard Law Review. His acculturation, bearing, mannerisms, beliefs, and thought processes have little relationship to most black americans, who have a sub-culture of their own. His sub-culture is that of White America, make no mistake about that. To claim that he's racist is absurd, in the extreme. doing so merely reveals the desires of the accuser to label Obama as a fantasy stereotypical "Black Man", which he's obviously not.
