"[W]e have seen Mrs. Palin on the national stage for seven weeks now, and there is little sign that she has the tools, the equipment, the knowledge or the philosophical grounding one hopes for, and expects, in a holder of high office. She is a person of great ambition, but the question remains: What is the purpose of the ambition? She wants to rise, but what for? For seven weeks I've listened to her, trying to understand if she is Bushian or Reaganite—a spender, to speak briefly, whose political decisions seem untethered to a political philosophy, and whose foreign policy is shaped by a certain emotionalism, or a conservative whose principles are rooted in philosophy, and whose foreign policy leans more toward what might be called romantic realism, and that is speak truth, know America, be America, move diplomatically, respect public opinion, and move within an awareness and appreciation of reality.
"In the end the Palin candidacy is a symptom and expression of a new vulgarization in American politics. It's no good, not for conservatism and not for the country. And yes, it is a mark against John McCain, against his judgment and idealism."More here.
