Obama was the DNC dilemma
Do I vote for the black guy or the white chic?
It wasn't a dilemma at all. Obama didn't win because he was black.
He won because he was the one who said, "Iraq was a really, really stupid idea' before it was cool to say that. And while Hillary and McCainiac were trying to thread the needle of why the war was a good idea but they still let Bush fuck it up, Obama was the guy who could get out there and say, "I said it was a bad idea, and I'm going to end it."
That's why he won.
Oh, it also helped that the bottom dropped out of the economy.
