This isn't exactly an original idea, but I think it's worth repeating ...  It's clear to me that old-school "civil rights leaders" like Jackson and Sharpton feel threatened and jealous of Obama. 

But rather than be a problem for Obama, this is actually an opportunity.  Jackson and Sharpton have long ago lost any claim to legitimacy that they might have once had.  In fact, picking a fight with Jackson would probably benefit Obama. 

I've personally heard Republicans tell me that the good thing about having Obama win is that it would officially end the reign of Jackson and Sharpton ...
