(CNN) - After playing coy in an interview with CNN's Paul Vercammen Tuesday night, Sarah Palin revealed on Fox Business Network that she voted for Newt Gingrich in Alaska's caucuses on Tuesday.
"Newt is whom I chose up here in Alaska to best represent the ideas that many Alaskans want to see, the preferred presidential candidate in this area. That's who I cast my vote for," Palin said.

Earlier Tuesday, the former Alaska governor was interviewed by CNN shortly after she voted at a caucus site in Wasilla, but refused to say who she picked in the state's contest.
But later in the evening, she had an apparent change of heart when asked about her vote by Neil Cavuto on Fox Business Network.
"I knew you were going to ask me that, and I am just the poorest, politician-sounding pundit. It is tough for me to spin out of a question like that when it comes from a Fox reporter. If it comes from another reporter, I can spin out of it. But since it came from you, I will tell you, I won't sound like a politician and I will tell you who I voted for tonight."
Palin's husband, Todd, endorsed Gingrich in January, and the former governor made headlines shortly before South Carolina's primary when she urged voters to turn out for the House speaker in order to defeat Romney and keep to nominating process going.
On Tuesday, Palin said Gingrich was best equipped to "bust through that radical left dispensation and desire to mistreat those who are defenseless, mistreat those who have disadvantages."
Referring to him as "the cheerful one," a label Gingrich gave himself during CNN's Arizona debate last month, Palin said she appreciates "what he has stood for."
"He has been the underdog in many of these primary races and these caucuses. My preference tonight was for the cheerful one," Palin said.
She added that her husband was an independent and did not vote in the Republican contest on Tuesday.
Palin ran as Republican Sen. John McCain's running mate in the 2008 presidential election. While McCain is now backing Mitt Romney, Palin said she would support Romney if he were to secure the nomination.
"If Romney is the nominee, I hope I get to stand side by side with John McCain, whom I do respect, stand side by side with him in supporting Romney as our nominee," Palin said.
