"95% of Afro Americans supported President Obama (coincidence?)"
Nope. Not coincidence at all. The GOP ran against Obama using "dog whistle" phrases, and in the end even gave up on dog whistles, and was openly racist. Take a look at the Bill O'Reilly quote I posted above. That's the modern GOP.
Why in the world would anyone expect American blacks to vote for the person whose party is actively campaigning against them?!?
