Race For Santa Clarita House Seat Still Too Close To Call

LOS ANGELES (CBSLA/AP) – Rep. Steve Knight appears to be losing his battle to hang on as the last Republican congressman in the nation's most populous county.

Democrat Katie Hill, who has not previously held public office, appears to have won the seat by 51.3 percent, but election officials have not yet called the race for the newcomer.

Democrats hold a registration edge in the 25th District, which cuts through suburbs, horse ranches and high desert in northern Los Angeles County and a small slice of Ventura County.

Knight's family has been involved in local politics for decades — a high school is named after his father, a former legislator and test pilot.

Hill stressed her centrist politics: She's a gun owner and her Republican father is a police officer who had never voted for a Democrat before her primary. Her mother, a Democrat, is a nurse.
