Personally, I think it's a mistake for Palin to campaign to McCain in AZ, but she's being gracious for having been catapulted to the national stage. She's allowed to show her gratitude, I suppose, but if she ever gives him this kind of support in the future then I've got to wonder about her....
He did not pluck her out of subarctic obscurity as a favor to her. He did it only because he thought it would benefit himself. She owes him nothing. Her rise is a result of who she is. The is nothing gracious or classy about supporting the evil that is McCain. There is nothing gracious or classy about contributing to the destruction of our republic, our future, our way of life.
