PHOENIX (AP) -- Two Arizona congressional races remained too close to call Sunday.
The hand-picked successor of former Democratic Rep. Gabrielle Giffords was ahead again in his race to win a full term in Arizona's 2nd Congressional District.
Results posted Sunday show Democrat Ron Barber pulling ahead of Republican Martha McSally by more than 300 votes out of more than 250,000 cast in the 2nd Congressional District race. The district covers parts of Pima and all of Cochise County. Pima County expects no vote tallies Sunday and Cochise County officials were unavailable.
