Two critical political debates occurred at the same prime-time hour on local television Saturday night. On WREG-TV, News Channel 3, Memphis and Shelby County viewers could watch a live feed from Nashville of the U.S. Senate debate between former Chattanooga mayor Bob Corker, the Republican, and U,S. Rep. Harold Ford Jr. the Democrat. Over on WMC-TV, Action News 5, the three candidates for Rep. Fords 9th District congressional seat Democrat Steve Cohen, Republican Mark White, and independent Jake Ford were having at it. Both encounters had their fair share of fireworks for the attentive viewer.
