Sarah Palin endorsed California Senate candidate Carly Fiorina (R) via Facebook Thursday.

"California is still Reagan Country, and Carly promises her 'Reagan Conservative' values will be put to good use for her state and for our great nation," the former Alaska governor wrote. "Shaking it up in California is long overdue. Let's help Carly do it!"

Fiorina said she was "honored and grateful" to Palin's backing.

"She, too, is a political outsider and a strong fiscal conservative, and we share a common concern for the direction our country is headed in under Barbara Boxer and her allies in Washington," Fiorina said in a statement. "Californians across the state have had enough of Washington insiders and their political games, and together, I am confident we will help restore integrity to our nation's capital by bringing Barbara Boxer's 28-year career to an end."

Palin's note includes links to Fiorina's website and Twitter feed but does not say to donate directly to her campaign.

This is the second major conservative endorsement in as many days for Fiorina. On Wednesday her campaign announced it was being supported by National Right to Life, a powerful anti-abortion group.

A spokeswoman for the Fiorina camp said no campaign events with Palin have been scheduled.
