Peggy Noonan writes in The Wall Street Journal:
There is still a sense about Mr. Obama that he needs George W. Bush in order to give his presidency full shape and meaning. In this he is like Jimmy Carter, who needed Richard Nixon, or rather the Watergate scandal, which made him president. Mr. Carter needed Richard Nixon standing in the corner looking like he’d spent the night sleeping in his suit as it hangs in the closet. The image is from Joe McGinnis’s “The Selling of the President, 1968.” Mr. Carter needed to be able to point at Nixon and say, “I’m not him. He dirty, me clean. You hate him, like me.” Carter’s presidency was given coherence and meaning by Nixon, Watergate, and without it that presidency seemed formless. Mr. Obama, in the same way, needs Mr. Bush standing in the corner like Boo Radley, saying “Let’s invade something!” But Mr. Bush is wisely back home in Texas finishing a book, and the president never sounds weaker than when he suggests his predicament is all his predecessor’s fault.
