Sarah Palin said Ruth McClung “is the smart choice” against U.S. Rep. Raúl Grijalva.

She posted the new endorsement and eight others on her Facebook page today. She’s also supporting Janet Contreras, who’s running against Ed Pastor in Arizona’s Congressional District 4.

McClung took to her Twitter account to thank Palin for the endorsement.

Palin brought up Grijalva’s call for a boycott when SB 1070 passed, a central theme in McClung’s campaign against him.

“Ruth’s commonsense fiscal approach to job creation and reining in reckless government spending is in sharp contrast to her opponent’s liberal record. In fact, Ruth is running against a four term incumbent who is so out of touch that he actually called for a boycott of his own constituents.”

Grijalva said the endorsement further distinguishes the two candidates.

“It will bring her more money, but it creates an urgency among people who don’t want that philosophy in office,” he said. He said he’s comfortable being one of Palin’s targets.
