"It's really sad when Republicans don't want to rally behind a black conservative that has a chance to win."
What does him being black have to do with anything?
Most blacks think that conservatism is white-middle-class-guy thing. It would be good to have somebody from their rank to show that conservatism cut across race/ ethnicity. Yes, we have several black authors (e.g. Sowell), but not many elected public officials.
If you really have to ask that question, then you're just not ready for prime time, player. This is politics, get it?
