PHOENIX -- Arizona's three competitive congressional races remained too close to call in early returns, but voters in six other districts chose their representatives along the expected 4-2 party split in favor of Republicans.
The new Phoenix-area 9th District, Tucson-centered 2nd District and northeastern Arizona's 1st District were tight, although Republican Jonathan Paton was building a lead in early returns over Democrat Ann Kirkpatrick in the 1st.
Democrat Ron Barber has a small lead against Republican Martha McSally in the 2nd District, while Democrat Kyrsten Sinema was holding a slight edge in the 9th District.
Depending on the outcome, Democrats could end up with a majority of the delegation or Republicans could hold on or add to their current 5-3 majority.
The state earned a ninth seat after the 2010 Census and will fill it for the first time in November.
