California: What's needed to get a San Francisco mayoral recall on the ballot

There's a second attempt against Mayor Ed Lee (the first was killed because it was launched during his new term grace period). The article notes that petitioners would need 47,227 signatures in 160 days and that if a recall would succeed, the president of the Board of Supervisors will be interim mayor until the board appoints a new mayor. That official would be in office until the next citywide election.

Petitioners claim to have raised $2000 for the effort so far.
