Both black, criminally incompetent , Both used Cocaine,Both used their cronies for important positions in their administration, both got almost 100% of the black vote, both racist, is that enough?
Bill Clinton used cocaine. George Bush may have used cocaine. What I'm having difficulty with is why you compared Obama to Marion Barry, a crack addict and convicted felon. If it was primarily because both men are black, you are doing the rest of us on this website a disservice.
