I want to know the answer to the following question:
Which city was Gavin Newsom mayor of when he said Schwarzenegger was turning Democrat?
All the background I'm provided with is that "After hearing a speech by Schwarzenegger at the 2006 Martin Luther King, Jr. breakfast, San Francisco mayor Gavin Newsom said that, "[H]e's becoming a Democrat [… H]e's running back, not even to the center.". Is that enough to answer the question?
