Krauthammer may not ALWAYS be right, but he sure gave the President and Harriet Miers the rationale for "cover" in her withdrawal. His advice or observation formed the basis of putting right a disastrous situation. His view is the same as my hope: the third pick should be JRB.
Nobody believed the Bush spin about why Miers withdrew, so how effective a cover was it? That nomination was going down whether Krauthammer said a word or not.
