Obama and the Super Delegates

If you read Ed Richter's stories about the super delegates for Obama, he interviews several super delegates- (Mr. Hightower, Mr. Smith and Ms. Ford are mentioned). I realize that the focus of this particular story is on the reactions of the appointed super delegates, but one gets the impression that when Mr. Richter ( or any reporter at the Journal) interviews anyone concerning Obama, he/they seem to choose only African-American's to approach, as if they are the only ones with an opinion about Obama. Is the assumption, by these reporters, that because Obama is African-American that African-Americans have a monopoly in the opinion category? This is a trend that I have noticed about their brand of reporting and, frankly, I mention it out of curiosity.Why not ask the other groups what they think of Obama as a Presidential candidate as well? It appears that your reporting may be catering to one select group and that's not diverse opinion reporting , is it?
