There are more than 10 million people in Los Angeles County but just five elected Supervisors. With both legislative and executive responsibilities, they're some of California's most powerful elected officials. It's so difficult and expensive to run countywide that election is almost a lifetime job. Now 2nd District Supervisor Yvonne Brathwaite Burke is stepping down, and two political veterans -- LA City Councilman Bernard Parks and State Senator Mark Ridley-Thomas -- are in a tight race to replace her. We get an update on the race from Eddie Hager, creator of LeimertParkBeat.com.
