I came across this post from last year by the Gadflyer. It's a good read.
Basically, the few black conservative interest groups are, shall we say, pretty multicultural. And funded by a rather unusual group of racial healers.
Here's the money quote:
If you believe that the most pressing problems facing the African-American community today are the minimum wage, too many regulations on energy companies and too many people trying to get kids to quit smoking, then maybe you should join the black conservative movement yourself. You don't have to be black, or even know anyone who is.
