"how did Obama get his support up to 93% among blacks?"

Unless you believe that 93% of black people are merely idiots whom Obama can convince of anything, the proper question is "how did Clinton get her support down to 7% among blacks?"

Simply, she played the race card (remember her constant talk about Farrakhan and Wright?) to get white votes, and the black people decided not to forgive her about it; especially since she and Bill kept dismissing black people's votes as insignificant.

What, did you think the Clintons' constant dissing of black people's votes wouldn't have a further negative affect on Hillary in the next contests?

All the way to South Carolina she was getting like 30% of the AA vote I think -- and why shouldn't she? Even going by demographics alone, half the black people are women you know, with as much demographic reason to support Clinton as they had for Obama.

But then the Clinton policy of dissing the states and demographics that didn't vote for Hillary began in earnest, and using the race cards of Wright and Farrakhan -- and she got punished for it, by losing all black women as well.

"A large majority of whites, hispanics, asians voted against Obama."

In some places. In other places he's won majorities of white people in several lily-white states, and he's gonna win the majority of white people again in Oregon and South Dakota.

Besides blacks, a large majority of young voters, well-educated voters, and liberal voters voted in favour of Obama -- strangely enough they are the demographics least likely to be racist, no?

Besides women, Hillary has the older voters, the conservative voters, and the less-well-educated voters -- strangely enough the demographics most likely to be affected by race in their choice.
