Palin's off-script comments irk McCain aides - CNN.com: "A Palin associate, however, said the candidate is simply trying to 'bust free' of what she believes was a damaging and mismanaged roll-out.
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."
