A question for McCain's fans in the press corps

Out of general fondness, the Washington press corps (which is not just a phrase but a definable community of people) has for almost a decade graded John McCain on a curve, especially in the last eighteen months when he’s slipped perceptibly. Now, in response to the bludgeoning and campaign of falsehoods his campaign has unleashed over the last ten days, a number of his longtime admirers in the punditocracy have written articles either claiming that they’d misjudged the man or lamenting his betrayal of his better self.
