Yet it is dangerous to ask for a president who never changes his mind. The evidence on this point is obvious and fresh. President George W. Bush watched his father reverse himself on the “Read my lips: no new taxes” pledge and pay the price, losing re-election in 1992. His son overcompensated by refusing to reverse course on anything—even when the weight of facts and history and reason commanded it. A flip-flop or two from George W. Bush might have gone a long way.
