SAN FRANCISCO (BCN) — Four tightly contested races for San Francisco’s Board of Supervisors remained close Tuesday.

The city’s 11-member legislative body will get four new members in January and could decide who will be the interim mayor until a replacement for current mayor and lieutenant governor-elect Gavin Newsom is chosen in the next mayoral election in November 2011.
