The race for Mayor of San Francisco is even more crowded, now that Board of Supervisors President Aaron Peskin has joined the field. Peskin is the only major progressive who’s challenging Mayor London Breed.

There are three moderate candidates trying to unseat Breed, including philanthropist Daniel Lurie, former Mayor Mark Farrell and Supervisor Asha Safai, though Safai has been trying to move to the left in this campaign.

We’ve had Lurie and Farrell and Mayor Breed on this program, and today we are joined by the newest person in the race, Supervisor Aaron Peskin.
