4th District, L.A. County Board of Supervisors
Matchup: Rep. Janice Hahn vs. Steve Napolitano
Dynamic: Term limits are forcing Supervisor Don Knabe out of office and creating a vacancy in this district for the first time since 1996. Many observers believed Hahn would win the seat outright in the June primary, but Napolitano, a longtime aide to Knabe, finished better than expected thanks to the backing of his boss and substantial financial resources. Hahn has served three terms in Congress.
Interesting fact: Kenneth Hahn, the congresswoman’s father, served on the Board of Supervisors for 40 years.
