PHOENIX -- Republican state Sen. Ron Gould says he's entering the race for his party's nomination for the 4th Congressional District seat.
Gould's announcement on Wednesday was expected and sets up a three-way GOP primary race with Pinal County Sheriff Paul Babeu and current 1st District Rep. Paul Gosar.
Gosar announced he was moving to the 4th District on Saturday. Redistricting had made the 1st District more Democratic and a tougher seat for the first-term congressman to win.
The newly drawn 4th District is heavily Republican and runs from western Arizona through Prescott and south to take in parts of Pinal County south of Phoenix.
Gould is from Lake Havasu City in northwest Arizona. He was elected to the state senate in 2004 and previously was a Lake Havasu City councilman.
