Former Alaska Gov. Sarah Palin announced her backing of three more Republican women on her Facebook page Thursday night.

In a post she called "a new 'Mama Grizzlies' field report," Palin endorsed Rep. Cathy McMorris Rodgers (R-Wash.), Rep. Mary Fallin (R-Okla.), who is running for governor, and California Republican congressional candidate Star Parker.

About McMorris Rodgers, Palin wrote, "I have a deep respect for Cathy's strong voice for families who are touched by those with special needs." Both Palin and Rodgers have sons with Down syndrome.

"I heartily endorse these liberty loving 'Mama Grizzlies,' " Palin wrote.

Palin has made a habit of wading into Republican primaries this election cycle. She recently endorsed attorney Joe Miller in his primary against Sen. Lisa Murkowski in Palin's home state of Alaska. And in Washington state, Palin backed Tea Party favorite Clint Didier over Dino Rossi.

But this new spate of endorsements comes in races without a whole lot of political drama. In Oklahoma, Fallin is the favorite in the governor's race. In California, Star Parker is a long shot to defeat Rep. Laura Richardson (D). And McMorris Rodgers occupies a safe Republican seat.
