On the left is a picture of D.C. Mayor Adrian Fenty, whose ancestors journeyed to Earth from the same planet as Vin Diesel's people. (By the way, have you ever noticed how Vin Diesel looks like Jerry Seinfeld -- not in pictures, so much, but in terms of facial expressions?)
In the pictures on the right is Fenty's 67-year-old challenger Vince Gray. As you can see, the only thing black about Gray is his hair color.
And then there's the mayor of Cleveland, Frank G. Jackson, who is humorously known as one of the leading African-American politicians in Ohio, although in a previous career, he was the white Maoist intellectual behind a Latin American indigenous peasant uprising, or at least that's what he looks like to me.
