Yes, I know President Obama is black, but why did it take so long for a black person to become president in the first place?

For answers to that question I point you to an interview by the WSJs Jason L. Riley with George Mason University Professor Walter E. Williams and a presentation by John McWhorter, associate professor of linguistics at the University of California, Berkeley and a contributing editor to the Manhattan Institute’s City Journal. Mr. McWhorter’s presentation is the effect the War on Drugs had on blacks in America. PDF version, podcast.
