PHOENIX (AP) _ Former Arizona Rep. Ruben Gallego has won the Democratic primary in the 7th Congressional District, essentially assuring he takes the seat in the left-leaning Phoenix-area district.
Gallego faces no Republican opposition in November's election in the Democratic stronghold held by retiring Rep. Ed Pastor.
The 34-year-old Gallego survived a tough challenge from onetime Maricopa County Supervisor Mary Rose Wilcox.
He is the son of Hispanic immigrants who was the first in his family to go to college. He later served in Iraq.
Gallego campaigned on curtailing the rising cost of college education, making sure veterans get timely health care and improving the lives of the poor.
