Sarah Palin is psychiatric.

There are many unanswered questions here and her behavior vis-a-vis the 'going off the reservation' is consistent with her narcissism, her pathological lying, and her manipulative, sociopathic behavior.

Palin’s sudden rise to prominence, however, owes more to members of the Washington élite than her rhetoric has suggested. Paulette Simpson, the head of the Alaska Federation of Republican Women, who has known Palin since 2002, said, “From the beginning, she’s been underestimated. She’s very smart. She’s ambitious.” John Bitney, a top policy adviser on Palin’s 2006 gubernatorial campaign, said, “Sarah’s very conscientious about crafting the story of Sarah. She’s all about the hockey mom and Mrs. Palin Goes to Washington—the anti-politician politician.” Bitney is from Wasilla, Palin’s home town, and has known her since junior high school, where they both played in the band. He considers Palin a friend, even though after becoming governor, in December, 2006, she dismissed him. He is now the chief of staff to the speaker of the Alaska House.

Upon being elected governor, Palin began developing relationships with Washington insiders, who later championed the idea of putting her on the 2008 ticket. “There’s some political opportunism on her part,” Bitney said. For years, “she’s had D.C. in mind.” He added, “She’s not interested in being on the junior-varsity team.”

During her gubernatorial campaign, Bitney said, he began predicting to Palin that she would make the short list of Republican Vice-Presidential prospects. “She had the biography, I told her, to be a contender,” he recalled. At first, Palin only laughed. But within a few months of being sworn in she and others in her circle noticed that a blogger named Adam Brickley had started a movement to draft her as Vice-President. Palin also learned that a number of prominent conservative pundits would soon be passing through Juneau, on cruises sponsored by right-leaning political magazines. She invited these insiders to the governor’s mansion, and even led some of them on a helicopter tour.
