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."
So, at least I'm not the only person who realised it!
