I just want to say the aides who are attacking Sarah Palin are the most unprofessional people in the world. They are just developing excuses to save their own skin for a future job.
As a handler, spokesperson, etc. you are exposed to many things and you never, ever allow that to get out in the public. But they are going one-step further, manufacturing things. As Campbell Brown reiterated, CNN has already been able to disprove several of the claims.
I think Campbell Brown nails it in this comment.
Some people just need to grow up, accept responsibility and move on to the next job.
