Mayor Ed Lee named District 4 Supervisor Carmen Chu as the city’s assessor-recorder, effectively replacing onetime mayoral candidate Phil Ting. Chu, who would often correct Supervisor Jane Kim's math during Board of Supervisor meetings, seems like a natural fit for the numbers-focused gig. "She is smart, methodical and solutions-oriented," beamed fellow Supervisor Scott Wiener.

As for the ramifications of this move? SFGate's John Cote has more:

The move sets off a mini political cascade at City Hall, with attention shifting to who the mayor will appoint to fill Chu’s seat on the Board of Supervisors for District Four, which includes the Sunset and Parkside neighborhoods.

It also sets the stage for November elections for both posts - unless a special election is set sooner for another reason - and for maneuvering by potential challengers.

The job change will also give Chu a bump in salary going from $105,723 to $173,736, according to SFGate.
