I'm thinking President Obama is in Africa this week just waiting for Nelson Mandela to die, so that he can be photographed as being "Johnny on the Spot", ala Je$$e Jack$on, re: MLK.
In other words, Obama is there to wave the bloody shirt and assume the mantle of Universal Uber Black Icon just as soon as Nelson gives up the ghost.
This explains a few things....especially why this "official visit" seems to be going on forever.
That is how desperate Barack Obama has become to establish some sort of "Legacy": he's willing to waste $100 million to travel halfway around the world and hover over Mandela's deathbed like a fucking vulture. For....?
Oh, right: so someone can snap that dramatic picture (we can only hope it's black and white, because that makes it ever so much more 'dramatic') of Obama paying homage to the Great Man of History while simultaneously picking up his fallen mantle. If they can get Winnie Mandela to even be within seventeen feet of Odoofus (dare we dream? Perhaps actual physical contact between the two?), it's an even better image.
Maybe Morgan Freeman can reprise his typical "Magic Negro" role in the film version?
Otherwise, one wonders why Obama didn't just mail the usual ironclad-claptrap-semi-retarded speeches in? It's not like he's had anything to actually say to these folks that he hasn't already worn our ears out with, is it?
