(CNN) - She may not be publicly endorsing a candidate for president, but Sarah Palin clearly has a favorite in the ongoing campaign feud between Mitt Romney and Newt Gingrich.
In a post on her Facebook page Friday, the former Alaska governor praised Gingrich's Ronald Reagan connections, while questioning Romney's conservative credentials. Ultimately, Palin said the GOP establishment backing Romney were "cannibals" for attempting to discredit Gingrich.

"I am in favor of contested primaries and healthy, pointed debate," Palin wrote. "They help focus candidates and the electorate. I have fought in tough and heated contested primaries myself. But what we have seen in Florida this week is beyond the pale."
Palin, whose husband Todd endorsed Gingrich earlier this month, said tactics used against the former House speaker were reminiscent of attacks against her during her vice presidential bid in 2008.
"The difference in 2008 was that I was largely unknown to the American public, so they had no way of differentiating between the lies and the truth," Palin said. "All of it came at them at once as 'facts' about me. But Newt Gingrich is known to us – both the good and the bad."
Gingrich's relationship with Nancy Reagan, along with an endorsement from Reagan's son Michael, should speak to the former speaker's record as a conservative, Palin argued.
"There are no two greater keepers of the Reagan legacy than Nancy and Michael Reagan," Palin wrote. "What we saw with this ridiculous opposition dump on Newt was nothing short of Stalin-esque re-writing of history."
Borrowing one of Gingrich's favorite campaign lines, Palin said the mainstream pillorying of Gingrich was "Alinsky tactics at their worst," referencing the radical community organizer Saul Alinsky, who Gingrich namedrops frequently on the stump
Palin boiled down the race to a tug-of-war between mainstream Republicans backing Romney, and grassroots activists unwilling to fall in line behind the establishment pick.
"I respect Governor Romney and his success," Palin wrote. "But there are serious concerns about his record and whether as a politician he consistently applied conservative principles and how this impacts the agenda moving forward. The questions need answers now. That is why this primary should not be rushed to an end. We need to vet this."
Palin ended months of speculation in October when she announced she wasn't seeking the GOP presidential nomination. Political observers have been looking for an endorsement from the former governor ever since, but have thus far been left hanging.
