Nixon's grand mistake was his failure to understand that Americans are forgiving, and if he had admitted error early and apologized to the country, he would have escaped.

There may yet be another Watergate book. I have thought a book about the aftermath of Watergate and its impact could be done, perhaps by me or someone else.

After Nixon resigned in 1974, he engaged in a very aggressive war with history, attempting to wipe out the Watergate stain and memory. Happily, history won, largely because of Nixon's tapes.

I suspect there have been a number of conspiracies that never were described or leaked out. But I suspect none of the magnitude and sweep of Watergate.

Nixon had some large achievements in foreign affairs. They will be remembered. But a president probably gets remembered for one thing, and Watergate will head the Nixon list, I suspect.

People like to pigeonhole and say, Well, I'm a Washington insider, and you know, that's quite silly. What does that even mean?

I think the problem in the Republican Party is really not money. I think they've got lots of it. I think it is theory of the case - why are we here, what is our message, how to connect to the real world.
