Sarah Palin votes for Gingrich in Alaska

Sarah Palin surprised caucus-goers in Wasilla, Alaska, on Tuesday when she showed up at her local polling location, casting her ballot for former House Speaker Newt Gingrich.

Palin's husband, Todd Palin, has endorsed Gingrich, and Palin has been generally supportive of the former Speaker.

"To be perfectly honest with you, and candid, not being political, I will answer your question, I will let you know I voted for the cheerful one, Newt Gingrich," Palin told Fox News early Wednesday morning, although she insisted that was not a formal endorsement.

CNN had a reporter and camera crew at the caucus site, and Palin, a Fox News contributor, stopped to talk to them. But with CNN, she was elusive about her vote.

"I would not tell you who I voted for in this presidential preference poll," she said, although she reiterated comments she had made earlier in the race about wanting to see the "process continue." 

"I want to see the process continue, more debate on who it is who can bust through the Obama Orwellian rhetoric and pandering," Palin said.

Palin also dismissed concerns the bruising primary process could hurt the eventual Republican nominee.

"I do believe competition makes all of our candidates better," Palin said.

The former governor went on to say that it was possible she could rejoin the national conversation with a 2016 presidential run.

"Anything in this life, in this world, is possible," Palin said. "Anything is possible for an American. I don't discount any idea or plan that at this point isn't in my control … I would seriously consider whatever I can do to help this country."

Palin was also asked about her reaction to the controversy surrounding comments talk show host Rush Limbaugh made about a female Georgetown law student testifying in favorite of federal funding for contraception. Many conservatives have called the outrage over Limbaugh's comments unfair after liberal commentators including Bill Maher had described Palin in unflattering terms.

"I think the definition of hypocrisy is for Rush Limbaugh to be called out … and never is that applied to leftist radicals who say such horrible things," Palin said.
