Flake wades into Calif. Senate GOP primary

The endorsement war continues in the California Senate Republican primary.

Conservative state Assemblyman Chuck DeVore announced Thursday he's got the support of Rep. Jeff Flake (R-Ariz.).

The announcement came two days after Condoleezza Rice revealed she's backing Carly Fiorina's (R) Senate bid.

"We know that Barbara Boxer is more vulnerable in 2010 than ever before -- and we know that California's Republicans have an array of viable options for beating her," Flake said in statement. "I encourage them, and all conservatives, to join me in supporting the candidate who has been battle tested. That candidate is Chuck DeVore, and he has my full support."

DeVore thanked Flake for his support. "As this campaign continues, it becomes increasingly clear that I am the only real conservative in this race," he added.
