Why can't you be more like Nixon?
Falling firmly into the category "he-should-know," John Dean on Bill Moyer's NOW (scroll down a ways to find this interview in the transcript):

"I have no grudge against any of these people at all. I'm just I'm deeply disappointed in them. Deeply disappointed. And a bit frightened by them.

BILL MOYERS: You-- how so?

JOHN DEAN: That they absolutely won't, you know, what the world opinion is, is irrelevant to them. What the Americans' opinion, other than their base, is irrelevant.

They're on their own wavelength, and not listening. And they're men of zeal, while I think in their hearts they believe they're doing the right thing. This is the most dangerous kinda situation.

When you move in secrecy and you're not taking outside advice, when you get that bunker mentality, which I'm sure you saw in the Johnson administration, we saw in the Nixon White House. This is when you make bad decisions.

If not for the Clarke book, I wonder if this new book by John Dean, in which among other things he charges that Bush/Cheney should be impeached for lying to Congress about going to war, would be getting all the press. He claims the Bush administration has been dirtier, more secretive and more criminal than Nixon's.

Other than that he thinks they're alright guys.
