I'm not sure how many people in setting in the semi-circle are running for President of El Paso ("mayor" no longer covers the office's duty). Given their new position where to build the arena, I would say all of them.
So the ankle biters win for once - awesome for them.
The taxpayer still loses because they didn't cancel the whole thing. The convention center sits empty most of the time and now there will be an empty arena to keep it company.
