Sarah Palin has made some political moves that were emotionaly driven rather than politically well thought out. Supporting McCain in AZ, for example.
Peoples overreaction to the McCain endorsement is emotionally driven and not well thought out. If pull there heads out of their collective naval, they will be able to see that Sarah did what she had to do. End of story.
And HOW do you know that??? Every move she has made has been carefully calculated on political risk-cost-return basis.
