Sarah Palin Makes News Over Possible Presidential Bid

Former Alaska Gov. Reveals Vote for 'Underdog' Newt Gingrich

Could Sarah Palin be considering a run for the presidency?

"Anything is possible," Palin told CNN in an exclusive interview at her polling station in Wasilla, Alaska on Tuesday regarding a 2016 presidential run.

Palin also added that she "wouldn't close any doors" if any of her fellow Republicans were unable to lock down a nomination, or if any nominee wanted her to partake as a candidate in the upcoming election.

The Super Tuesday interview with the formal vice presidential candidate was impromptu, and came unexpectedly for the news network. CNN was at the Wasilla polling station to cover the Alaska caucus vote on Tuesday evening when Palin showed up to cast her vote.

"I can't say there was an expectation that Sarah Palin would be there. We were there to cover the caucus and Sarah Palin showed up," CNN Washington bureau chief Sam Feist told The Huffington Post.

Palin refused to tell the news network who she voted for, but later told Fox Business Network that she voted for Newt Gingrich.

"I have appreciated what he has stood for, stood boldly for. He has been the underdog in many of these primary races and these caucuses and I've respected what he has stood for," she said.

"My preference tonight was for the cheerful one," she added.

Meanwhile, a new film depicting the 2008 presidential campaign is set to air on HBO on March 10.

"Game Change," is based on the best selling book, Game Change: Obama and the Clintons, McCain and Palin and the Race of a Lifetime, by authors Mark Halperin and John Heileman.

In the short trailers, Palin, who is played by actress Julianne Moore, is depicted as having breakdowns, throwing tantrums, and struggling with the newfound pressure of the campaign
