Correlation is not causation, but big black lesbian Donna Brazile, erstwhile Gore 2k campaign manager, said the pillars of the ever-spend-evermore Democrat Party were African Americans, organized labor, women and homosexuals.
And, you wanta try the math again? Blacks are 10% or so of the populace, and women are 50%+, so black’s (or any other ethnic minority’s) votes tip the balance further than women’s?
Looks like I’m going to have to do the math for you. Obama had record female and black support: 95-5 for blacks, 55-43 for whites. Here’s a story with that breakdown:

So he actually won by a 90% margin of the 12% of the vote that is black: .9 x .12 = .108.
He also won by a 12% margin the 53% of the vote that is white: .12 x .53 = .0636.
That works out to 11% vs. 6% of the total vote.
