San Francisco's young and charismatic mayor, Gavin Newsom, has suffered his share of punches for taking bold positions on controversial issues. In this Stanford Center for Social Innovation sponsored audio lecture, Newsom tells of the courage and persistence it takes to make real social change as a leader. He outlines progressive reforms in areas such as education, health care, and business, and reflects on the personal and professional price paid for supporting one particularly contentious issue: gay marriage.
