Tom Berryhill is in and Mike Villines is out of the race to replace state Sen. Dave Cogdill, R-Modesto, who is leaving the upper house after one term.

Berryhill, a second-term Republican Assembly Member from Modesto, announced his Senate campaign in a statement issued Wednesday. First on his to do list is moving, or at least finding an address to register to vote in the 14th Senate District. He now lives just outside the district.

"He's in the process of moving now," said his campaign consultant, Steve Presson.

Villines, a GOP Assembly Member from Clovis, had toyed with entering the race, but opted against it to continue his run for state insurance commissioner.

"I want to continue that work so that I can serve at a level where I can have a strong positive impact for working families and taxpayers across all of California," he said in an email.

As of now, Berryhill will have just one opponent in the GOP primary in June. Heidi Fuller, a former utility industry consultant from a small town near Sonora, had filed papers to challenge Cogdill before Cogdill dropped out.

The heavily Republican 14th District runs from Kings Canyon National Park through eastern Fresno County and Clovis, north to Lodi. More than half of registered voters in the district live in Fresno County.
