According to this view, if you're a former Bush supporter who now says, as Mr. Bartlett did at the Cato event, that "the administration lies about budget numbers," you're a brave truth-teller. But if you've been saying that since the early days of the Bush administration, you were unpleasantly shrill.
Similarly, if you're a former worshipful admirer of George W. Bush who now says, as Mr. Sullivan did at Cato, that "the people in this administration have no principles," you're taking a courageous stand. If you said the same thing back when Mr. Bush had an 80 percent approval rating, you were blinded by Bush-hatred.
