Hey, we know that when you’ve announced your retirement, you can pretty much get away with anything. But, when you’re the mayor of a major city, you should probably try to not go totally three-year-old with your tantrums.

Like Tom Potter just did. In the midst of the council hearing on whether to continue the Interstate/Chavez renaming process for another several months, Potter up and split, leaving his colleagues at the dais completely stunned.

Here’s how it went down, according to Amy Ruiz, who was sitting in the session:

Potter: “I don’t feel really relevant to this conversation.”

“You’re the mayor of this city,” Leonard responded, pointing out that he’s incredibly relevant to this discussion.

“I don’t think this is appropriate,” Potter says, getting up and walking out. Sten stopped him: “I’m trying to find a way to work with you, and you’re walking out on this discussion?”

Potter said something in return, inaudible from the chamber, and left.

“I’m a little stunned of the mayor walking out when I was about to support his position, but it makes it difficult to support his position if he’s not here,” Sten says.

Now, the vote is completely up in the air. Sten supports more process on the name change, but not as much as proposed in Leonard and Adams’ resolution today. Obviously, Sten’s no longer in a position to do Potter any favors, so the three remaining commissioners agreed to pull the item off the table and return with a compromise idea on the morning of November 14th.

Interestingly, that’s one day before Potter had scheduled his vote on renaming Interstate. He no longer has the votes—that’s what you get when you take your ball and run home—so he’ll probably be pulling it any way.
