Bill Bennett on Sanford, just now.

He quoted Chuck Colson on integrity:

Integrity is wholeness. Think about the Navy. You know what happens when a Naval ship takes off? Someone goes up to the captain on the bridge — the captain on the bridge says check for watertight integrity. And someone goes down through the ship and they check every single door to see that every door, every waterproof door, is sealed.
And they go back up and they say, “The ship has integrity.” Integrity means every part of your body. It does not mean every part of your life. It means every single part of your existence. All those water tight doors are shut tight. And then there is integrity. You cannot say that someone can do something on the private side of their lives without it having public consequences, because you’ve opened one of those watertight doors and that ship will eventually sink. A cheat in private is going to be a cheat in public. Someone who lies in private is going to lie in public, and you can’t trust someone who does that.
