The Kilkenny email is a media joke. Why would you read this and take what she says as factual? Have you questioned the writer's motives? It is pathetically frightful that anyone would read a random email such as this and not hesitate for a moment that it could be based on lies and jealousy.
Any person, rather in an elective office or not, has enemies. If Kilkenny were a close, personal friend of Palin, she would not have written the email. Therefore, one must conclude that she isn't her friend so deduction leads us to the conclusion that she is her enemy. Which then makes you believe that this letter was written by a bitter, jealous person. I, personally, wonder if this letter wasn't written at the direction of a democratic official. Maybe the letter was the craftiness of the same group that released Palin's personal information (SSN, etc.) to the public.
