That would be Joe Ureneck, who, for whatever reasons, never even bothered to try to run in the September preliminary and so is running as a write-in candidate on Tuesday (which I know thanks to his citywide mailing). Check out his Web site to see how he manages to make Ed Flynn look like a flaming liberal (be sure to check out his essay on the Common Sense of Senator Santorum).
Bay Windows interviewed Ureneck a couple months back.
