Bevan Dufty, a candidate for mayor of San Francisco, is believed to be one of the first openly LGBT candidates in the U.S. to feature his child in a televised campaign ad.  The ad, titled “Someplace New,” is shot underground in the city’s transit system known as Muni.

“This ad speaks to the importance of Muni in Bevan’s daily life — and in the daily lives of most San Franciscans including Sidney, his daughter,” the Dufty campaign said.

Dufty, a former two-term member of the Board of Supervisors, could become San Francisco’s first openly LGBT mayor.
