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.

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.
