Mayor for a day

When San Francisco mayor Willie Brown leaves the country, he appoints a temporary acting mayor, a title some see as an honorary role. But during Brown's recent trade trip to Asia, acting mayor Chris Daly went ahead and appointed two environmentalists to the Public Utilities Commission--former Sierra Club president Adam Werbach and architect Robin Chiang. Within 20 minutes of the swearing-in ceremony, Daly's credentials as mayor were yanked.
