CNN's Rebecca Sinderbrand:

The candidate with the greatest white male support was the white man on the ballot. The candidate with the greatest support from white women was the white woman in the race. And black voters overwhelmingly voted for the African-American presidential contender.

But that doesn’t mean a person’s gender or race was a reliable predictor of how they would cast their vote. John Edwards didn’t capture a majority of the white male vote, winning the support of 43 percent of that demographic. And Hillary Clinton didn’t capture a majority of the support from white women, winning 44 percent of their votes.

Barack Obama, however, captured an absolute majority of the black male vote, 82 percent. And despite speculation that black women might be torn between Obama and Hillary Clinton, 79 percent of them voted for the Illinois senator.
