The Republicans have allowed the Dems to acquire important and very large population blocs without even a peep. Most significant is the Black community. Obama SHOULD be a laughingstock among AA's if it wasn't that the gop has been erecting "no negroes" signs all over the place. In spite of this Blacks are nothing like as monolithic as most assume. However, if you are a Black who becomes a dentist, buys a 780k home in Castle Heights, statistically you disappear. Even should he be questioned by a researcher able to label him properly I have SEEN a college professor "explaining" how "common sense informs us" he is NOT TYPICAL so should you be doing a survey based on 2200 people nationally "it makes sense" to discard him.
