There are tons of crooked politicians in ALL political offices, and I'm pretty sure it wasn't just Black Americans that voted them in. It is most likely that sane, decent (well-informed) Black Americans (or any other 'minority') didn't vote for Obama.
On the other hand, Blacks were 'turned' against Whites in an effort to ensure their 'block' voting for Democrats(Socialists) by Democrats(Socialists) who don't care how many bodies line the streets, as long as THEY STAY IN POWER.
The DAY that we UNITE and realize who the real enemy is (and always was) we will have a chance at regaining our UNITED STATES.
Obama got 96% of the black vote, last doesn't leave much leftover.
