Two of Arizona's three competitive congressional races remain too close to call as ballot counting continued in a process that could take days.
The most surprising race was in Tucson's 2nd District. That's where Republican political novice Martha McSally was holding a slight lead against Democratic Rep. Ron Barber on Wednesday.
Barber won Rep. Gabrielle Giffords' old seat by a 7 point margin in a June special election and was favored to win Tuesday. But McSally surged to her slight lead late on election night.
Former Democratic Rep. Ann Kirkpatrick declared victory over Republican Jonathan Paton in the 1st District after the Associated Press called the race for her late Wednesday.
Paton did not conceded the race, but Kirkpatrick released a statement saying: "I thank my opponent, Jonathan Paton, for the spirited race he ran, and I extend my hand to the folks who voted for him – I will work hard to give them a voice in D.C. That's what representation is all about. It's about listening, about finding common ground, about working toward solutions."
Democrat Kyrsten Sinema and Republican Vernon Parker were in a virtual dead heat for the 9th District seat.
