It was an absurd theory that by cutting taxes you would increase government revenues, because the growth of the economy would create an overflow of taxes that would fall into the government coffers.

But presidents matter. That's one of the biggest lessons I learned being in the White House.

The George W. Bush universe of threats is a constantly expanding universe as he moves to politically higher ground, escaping from failure after failure. He's not only radical, but the consequences of his radicalism have been catastrophic.

When most people see the word "radical," they think that it must refer to something left wing. Some people also may think of it as referring to far right-wing marginal groups. But here we have a president of the United States [George W. Bush] at the center of power, sitting in the White House, who is a radical.

The incubator for terrorism, after the Middle East, is Europe, partly because of proximity, partly because of the existence of large Muslim communities there.

Clinton was very early on aware of the problem of international terrorism.

I call George W. Bush a radical because he is undertaking a fundamental transformation of our Constitutional system of government and of our longstanding policies that have been accepted for literally generations. He thinks to concentrate unaccountable power in the Executive. He thinks you alter the laws so that, as Commander in Chief, he can determine, under what he says are wartime conditions, what the laws are, which laws should be enforced, and declare by fiat what our policy should be, even abrogating longstanding international treaties.
