Democrats dream of capturing California districts

LOS ANGELES — On a recent Sunday evening, Katie Hill, 30, whose father is an L.A. police lieutenant in Beverly Hills, boarded a red-eye flight to Washington for frenetic fundraising and networking. She must really want to get into the House of Representatives. If she does, she will have defeated a two-term incumbent, Rep. Steve Knight, 51, who was an LA police officer for 18 years and is the last Republican in a district containing a significant portion of Los Angeles County.
