THIS IS INTERESTING: Tennessee gubernatorial candidate Roy Herron is switching to run for John Tanner’s congressional seat. Herron writes:

Professor Reynolds,

Tonight, my longtime friend and Congressman, John Tanner, announced he will not seek re-election to Tennessee’s 8th District.

Given the challenges facing this nation, this state, and this congressional district, I feel like I can help make a difference by serving in Congress. And so, I want to let you know immediately of my decision to run.

You deserve a much fuller explanation of my decision than I can give at this late hour. I will be back in touch with you soon to share more. For now, I respectfully ask for your consideration, your support, and your prayers.

Stay tuned. When I saw the subject line on the email — “Running For Congress” — I first thought he was writing to encourage my run for Tennessee’s 29th District. . . .
