Ye lord, how misinformation takes on a life of its own. Here's the timeline:

March of 2007, L.A. Times columnist David Ehrenstein writes a column about how he thinks Obama fits into the Magical Negro archetype. FWIW, Ehrenstein is a black man.

Never one to miss a chance to dance on the edge of a racial slur, fat boy Rush Limbaugh has a song recorded to the tune of Puff the Magic Dragon, in which an impersonator plays Al Sharpton bemoaning the rise of Obama, the "magic negro." Because a black dude said it first, he gets away with it.

And now people think Al Sharpton actually sang it. Ugh. A lie goes 'round the world while the truth is still getting its shoes on.
