Four years ago, San Francisco's energetic new mayor, Gavin Newsom, ordered the city to provide marriage licenses to same-sex couples. That decision has been debated all the way up to the California Supreme Court, and has had serious implications for Newsom's political career.

In this audio lecture, sponsored by the Stanford Center for Social Innovation, Newsom discusses the price he has paid for sticking to his progressive principles and, unlike most politicians, not taking the easier road of compromise and complacency. He also outlines the striking successes associated with his reforms in the areas of health care, education, poverty and homelessness, the environment, and business.
