William Saletan nails what I suspect is a key element in the debate over George W. Bush's leadership capabilities or the lack, thereof. An awful lot of folks, both Democrats and Republicans, have sided with Bush and come to regret it. Unfortunately for sane discourse, when they change their minds, the immediate accusation is that since they said one thing then and now say another, they can't be trusted.
While we're at it, The Center for American Progress, a liberal site, has posted this list of Bush "flip-flops." I have never bought the notion that if a politician changes his position, it is a sign of weakness or insincerity. In many cases, I see it as a sign of being open to new evidence and willing to change with the times. But those who cite it as a negative about John Kerry ought to be willing to admit that Bush has often taken both sides of an issue.
