You can add another adjective to describe Supervisor David Chiu, the once and future president of the Board of Supervisors: Survivor.
Chiu broke with progressives a number of times -- culminating in his support of Ed Lee for interim mayor, which led to a resurgence of interest in the game Donkey Kong. After seemingly burning his progressive bridges once and for all, Chiu shocked everyone by removing his name from consideration for district attorney. Maybe he knew something political observers didn't, as Chiu was today handily re-elected board president in two lightning quick rounds.
Voting in the first round shook down this way: Moderate Sean Elsbernd had four votes as did Chiu, and Supervisor John Avalos had three. At that point, Elsbernd withdrew his name from consideration -- as he later told SF Weekly, "I knew there weren't two votes that would come down from the sky and go my way."
At that point, most political observers in the room readied themselves for Chiu's victory speech. (Your humble narrator, it should be pointed out, had put his money on Avalos, just like he did two years ago).
