Blacks may be slightly irked, but they will do nothing against Obama. If he ran tomorrow he would still get 97% of the black vote - which is a disgrace.
Why do you say it's a disgrace?
Finding out the truth is not disgraceful. The truth is that the 21st century is going to be entirely about race, race wars are going to scourge the face of the planet, and Obama's 97% are very well aware of this and are acting accordingly.
It's unfortunate, it's not what we learned in school - but it's reality. It's not disgraceful for voters to act in their best interest.
Apparently it has become a religious meme in the black community that you MUST vote democrat and no matter what the big D party does the big R party is worse. Most would not dare to publicly question the meme, it would be like a white person in South Carolina in 1955 questioning the virgin birth of Jesus, equivalent to declaring that you want to be shunned by the entire community. It takes real courage to even admit doubts about a religious meme.
