Sarah Palin has added New Hampshire Senate candidate Kelly Ayotte (R) to her list of "mama grizzlies."

The former Alaska governor announced in a Facebook posting Monday that she's backing Ayotte.

"Kelly is the strongest commonsense conservative who can win in the fall," Palin wrote. "I knew I liked her when I met her earlier this year, and I know this Granite Grizzly will represent New Hampshire with distinction in Washington."

A short time later the Ayotte campaign released a statement from her saying she was "honored" to have Palin’s support.

Palin "is a reformer in every sense of the word, and she has always stood firm for the conservative principles of low taxes, less spending and personal responsibility," Ayotte said. "I'm running for Senate to put our fiscal house in order and to get our country moving in the right direction again, and I'm honored to have her support."

In other Senate races, Palin's endorsement has been a mixed blessing for Republican candidates. In California, for instance, Sen. Barbara Boxer's (D-Calif.) campaign has repeatedly cited Palin's backing of Republican Carly Fiorina as evidence she's too conservative for the Democratic-leaning state.
