Maybe he's ashamed of his White heritage. He had the chance to clarify the fact that he's bi-racial when Ferraro stated that he wouldn't be where he was if he weren't Black
<actually, he can clarify it at anytime if he'd like>. All he had to say was, "hey, I'm just as White as I am Black".
But he didn't...
Everyone's aware of that...well, maybe he's forgotten.
Of course, that would make him a Tom, and cost him dearly with the Black solidarity voting bloc.
The race card has been deployed. Original! Powerful!
What, 45 percent of Caucasians have voted for the Black candidate and 6 percent of Blacks have voted for the White candidate, yet it's the caucasians who have a problem with race...got it.

Makes perfect sense to those who find reason and logic challenging.
