“I think this is a temperature take on her popularity”
Possibly, but if she needed to get a read on her popularity, I think she received it when she was snubbed by all three conservative Republican candidates in Virginia. I tend to think it is about selling her book. If not, why the timing?
Of course this all about selling her book. The book is Sarah Palin's vehicle to get around the media and get her unfiltered message out to the people. She is using Oprah Winfrey as much as Oprah is using her.
