A legislative committee has advanced a bill that would ban the sale of shark fins - including shark fin soup - in California.  That bill, which has divided Asian lawmakers, heads next to the Senate floor.   The same fiscal committee also approved a measure that would give the state Insurance Commissioner the power to reject health insurance rate increases.  That heads to the floor of the upper house as well.  Legislation to allow some undocumented college students to qualify for public financial aid like Cal Grants also passed a committee and is headed to the Senate floor.  But a bill that would have asked voters whether to abolish the death penalty in California didn't fare as well.  The author withdrew the bill from consideration by a committee, saying the votes weren't there.
