Black vote for Obama

A friend of mine (who's black) commented:

Black people will vote for Obama.  Overwhelmingly.  Why?  Because at the end of the day, Obama and Clinton will both have enough money and media credibility to be heard directly by most voters.  And when black voters hear what they have to say, and how they say it, it is not even close.  And this is not a knock on Clinton.  I would say the same if Obama's opponent were Gore, Kerry, or the Bill Clinton of 1992.  What's different is Obama.  Can you imagine anyone else in national politics making that speech that you just excerpted [Selma]?  Cmon.
