Puzzling. But Ill still go with the idiot/sharpie theory instead of the ironic genius trying to get us to contemplate the situation.
I am 99% sure the idiot/sharpie theory is the correct one, just based on Occam's Razor.

Maybe it is really a pro-Bush statement, that Bush is elevating Black people by giving them greater opportunities, putting to rest the stereotypical "lazy *let's not go there*."
