UPDATE: Senator Bill Frist will not be appearing at this event. Gray Sasser will participate in a panel discussion with Carol Swain, Bill Ivey and Beth Harwell at noon on Sunday. WPLN's Jacqueline Fellows will serve as co-moderator and the broadcast will be made available to BBC World Wide stations. Post Politics apologizes for the misinformation.

In yet another fun little warm-up to Tuesday's Presidential Debate at Belmont University, two players in Tennessee politics will debate each other at the Frist Center this Sunday. However, unlike Jim Cooper and Bill Haslam, the two participants in this war of words have a history.

Gray Sasser was only 25 in 1994 when Senator Bill Frist riding a populist conservative rage of discontent unseat his Democratic Senate Leader-in-waiting father, Jim, in the race for U.S. Senate race that year.

This Sunday morning, Post Politics has learned, Gray Sasser, now the chair of the Tennessee Democratic Party, will finally get his change at revenge by coming into Bill Frist's "house" to debate the prospective candidate for Governor on domestic policy.

The debate will be be broadcast locally on WPLN but will also beam out over the globe on BBC's worldwide radio network. Be ready for fireworks.
