Obama played the black community and many other voter groups so he could gain power. He is a user and a tool. What has Obama done for blacks high unemployment, rising energy costs,collapse of housing industry, and creeping inflation. Many blacks are worse off now than before Obama was elected.
This is a bit of delicious schadenfreude (the tape of Farrakhan dissing Obama was awesome too).
Obamas already losing the white, hispanic, and women vote if you analyze recent polling data. If he loses even 5 10 % of the black vote he got in 2008, then the partys over.
