An interesting point from a comment on this article at the NYT:
...I have to tell my friends a true fact that most of you out there chose to ignore or dare not acknowledging, that is: America and Americans will not vote for a black candidate with a heavily sounding Muslim name who did cocaine in his youth and who has 1 year experience in the Senate.
You can spin Obama anyway you want and paint him anyway you want, but this is the narrative that my friends at the RNC will repeat ad nauseum and beat the American people will into submission. This same narrative cannot be used against Biden or Clinton or even Edwards.
Obama might win the primaries, but he will not win the general elections. This is politics and it has nothing to do with the personal or professional quality of Obama...
