With a $25 billion budget, the five members of LA County's Board of Supervisors serve more people than all but seven states of the Union. For decades, they've been almost immune to electoral challenge, but voter-passed term limits are now in effect and major change is in store. Zev Yaroslavsky is termed out of the Third District seat he's held since 1994, setting up what could be an intense political battle. Today, former Santa Monica Councilman and Mayor Bobby Shriver jumped into the race. He's the former brother-in-law of Arnold Schwarzenegger and the nephew of John F. Kennedy. Former State Assemblywoman and Senator Sheila Kuehl announced her candidacy for Zev Yaroslavsky's seat last April. Before starting her political career, she was Zelda on TV's The Many Loves of Dobie Gillis. She then went to Harvard Law School, and was the first openly gay person elected to the state legislature.
