Why would any politician endorse an opponent in a runoff election? One of the questions on many area political watchers’ minds since Nashville’s mayoral election has been whether any of the also-rans will publicly lend their support to either of the “finalists.”

I’d definitely like to know whom each of the former candidates will vote for, but now that Buck Dozier is off the fence about staying on the fence, it isn’t likely to happen. I’m having a hard time coming up with reasons why a candidate should make an endorsement, but I can think of plenty why it’s not a good idea to pick a side once the battle lines have been redrawn:

• Making enemies: Picking one candidate over another might come back to haunt you, especially if you pick the losing candidate. Why would Briley, Dozier or Gentry want to gamble their influence in the next administration on the razor-thin margin of a few hundred votes?
• Alienating your base: How happy would most of Briley’s camp have been to see him endorse Bob Clement? How happy would most of Dozier’s voters have been to see him endorse Karl Dean?
• Swallowing a bitter pill: It’s a rough transition to go from trying to take votes away from an opponent to publicly asking voters to give him more.
• Impropriety: Everyone will wonder what it took, if anything, to”earn” an also-ran’s endorsement. It might be easier to revisit your own agenda down the line if you haven’t made it look like someone’s just returning a much-needed favor.

The reasons I see for making an endorsement, at least in this race, are three: One, you’re convinced one candidate is significantly worse than the other to the extent that it would hurt the city if that candidate won the runoff; two, you want a job in the next administration and don’t mind the potential backlash from such a political pick-and-roll; and three, you’re absolutely not running for anything again and don’t care what anyone else thinks about what you do. Endorsing one candidate over another in such a close race is risking something else: your own political future.
