San Francisco holds its non-partisan mayoral election on November 8, 2011. On August 8, nine candidates were invited to debate each other at the Castro Theater. Terry Baum, a registered Green who has the backing of the San Francisco Green Party, was not invited. She was told there wasn’t enough room on the stage for a ninth chair. But then the incumbent (appointed) Mayor decided to run, and the debate organizers made room for a chair for him. So Baum brought her own chair, and she was permitted to participate. Some of the other candidates ceded some of their time to her. See this story. Baum is one of only two persons running for Mayor who is a member of any minor party. The other is Wilma Pang, a member of the Peace & Freedom Party.
