Below is more from The Associated Press:

Democrat Ron Barber has won a full term representing Arizona's 2nd District despite a strong run for the seat from Republican Martha McSally.

The race was tight for more than a week after the election but Barber steadily began pulling ahead. He had a 1,402-vote margin over McSally by Saturday and The Associated Press called the race for Barber.

Voters picked Barber to replace former Rep. Gabrielle Giffords in a special election in June. He's her former district director and has touted his lengthy history in the district, his moderate views and his strong backing for veterans and border security.

McSally is a former Air Force pilot making her first run for political office.

The district covers parts of Tucson and Pima County and all of Cochise County.
