If McCain wins he'd be the oldest man ever elected president, and so age has to be a consideration. For the moment, though, the concern is not McCain's physical age but his intellectual age -- his willingness to revise his views and grapple with the new. Costumed as George W. Bush, he goes around the country peddling a joke of a tax plan and a frightening foreign policy. Ideas matter, and on the Middle East, McCain not only has little to say that is interesting but, as he takes a swipe at Obama, a distinctly ugly way of saying it. He's driven his vaunted Strait Talk Express off the high road and into the mud.
