The Politico reported:

Four Republicans close to Palin said she has decided increasingly to disregard the advice of the former Bush aides tasked to handle her, creating occasionally tense situations as she travels the country with them. Those Palin supporters, inside the campaign and out, said Palin blames her handlers for a botched rollout and a tarnished public image — even as others in McCain’s camp blame the pick of the relatively inexperienced Alaska governor, and her public performance, for McCain’s decline.

The emergence of a Palin faction comes as Republicans gird for a battle over the future of their party: Some see her as a charismatic, hawkish conservative leader with the potential, still unrealized, to cross over to attract moderate voters. Anger among Republicans who see Palin as a star and as a potential future leader has boiled over because, they say, they see other senior McCain aides preparing to blame her in the event he is defeated.

“These people are going to try and shred her after the campaign to divert blame from themselves,” a McCain insider said, referring to McCain’s chief strategist, Steve Schmidt, and to Nicolle Wallace, a former Bush aide who has taken a lead role in Palin’s campaign. Palin’s partisans blame Wallace, in particular, for Palin’s avoiding of the media for days and then giving a high-stakes interview to CBS News’ Katie Couric, the sometimes painful content of which the campaign allowed to be parceled out over a week.

CNN reported more on Palin going “rogue:”

McCain sources say Palin has gone off-message several times, and they privately wonder whether the incidents were deliberate. They cited an instance in which she labeled robocalls — recorded messages often used to attack a candidate’s opponent — “irritating” even as the campaign defended their use. Also, they pointed to her telling reporters she disagreed with the campaign’s decision to pull out of Michigan.

A second McCain source says she appears to be looking out for herself more than the McCain campaign.

“She is a diva. She takes no advice from anyone,” said this McCain adviser. "She does not have any relationships of trust with any of us, her family or anyone else.

“Also, she is playing for her own future and sees herself as the next leader of the party. Remember: Divas trust only unto themselves, as they see themselves as the beginning and end of all wisdom.”

…

With the presidential race in its final days and polls suggesting that McCain’s chances of pulling out a win are growing slim, Palin may be looking after her own future.

“She’s no longer playing for 2008; she’s playing 2012,” Democratic pollster Peter Hart said. “And the difficulty is, when she went on ‘Saturday Night Live,’ she became a reinforcement of her caricature. She never allowed herself to be vetted, and at the end of the day, voters turned against her both in terms of qualifications and personally.”
