Maybe because of this story by liberal watchdog group Media Matters, crackpot author Jerome Corsi canceled his second appearance on the Memphis-based white supremacist, anti-Semitic radio show "The Political Cesspool" on Sunday.

The host of the show, James Edwards, proudly refers to his agenda as "pro-white," and once blogged that interracial dating is "white genocide," just to give you an idea where he's coming from.

Corsi's race-baiting, factually-discredited book "The Obama Nation"  (typical Corsi: "Obama wants to will all the white blood out of himself so he can become pure black") currently sits on top of the New York Times besteseller list -- perhaps artificially, through bulk sales.

The Southern Poverty Law Center has more on Corsi's previous appearance on "The Political Cesspool" here.
