David Ignatius: McCain has no principles. Picking Sarah Palin proves it.

In May 2006, after McCain had courted the Rev. Jerry Falwell in an effort to win conservative support, I asked him if he was bending his principles for the sake of winning. "I don't want it that badly," McCain answered. "I will continue to do what is right. . . . If that means I can't get the Republican nomination, fine. I've had a happy life. The worst thing I can do is sell my soul to the devil."

He was right.
