McCain voted against Bush's big tax cuts, but now says he supports extending them rather than risking damage to the economy. Flip-flop? Not if you believe, as Burkeans often do, that sudden and large policy changes deserve skepticism, but that when a policy becomes well established and woven into everyday life, as the tax cuts have, continuity should get the benefit of the doubt.
In the face of resistance from Bush and his own party, McCain fought heroically for a law restraining harsh treatment of terror-war detainees, yet more recently he voted against legislation imposing on the Central Intelligence Agency the same stringent ban on coercive interrogation that the U.S. Army observes. Hypocrisy? Not if you believe that brutal interrogation methods should be illegal, but that holding the CIA to the military's white-glove constraints, even in emergencies, goes too far the other way.
McCain, in short, is an antirevolutionary, not a counterrevolutionary. No wonder, then, he invoked Burke twice to an audience of skeptical conservatives?-or, perhaps more accurately, skeptical "conservatives." And no wonder some of them booed. To movement conservatives, McCain represented heresy. But to the conservative movement, he represented a return to home truth.
