The Bay Citizen-USF poll shows the 58-year-old Lee dominating the field just three weeks before the election. More than 31 percent of respondents say Lee is their first choice under the cities ranked choice voting process.
City Attorney Dennis Herrera is second at 8.1 percent, and Supervisor John Avalos is third at 7.4 percent. If Lee wins, he would become San Francisco's first elected Chinese-American mayor.
