Book excerpt: Renowned attorney and political critic Bruce Fein reveals the dangers our Constitution and our nation have faced courtesy of the Bush Administration and a Congress asleep at the switch. In blistering detail, he deconstructs the policies of Bush in the War on Terror--from the flouting of the Foreign Intelligence Surveillance Act to the crippling of the Great Writ of habeas corpus--and forecasts that the damage he's done is unlikely to be repaired quickly or easily. As Barack Obama takes office, there are questions that involve the very foundations of our government and the degrees to which they have been undermined, either actively or passively, by nearly everyone in power today. By exploring the constitutional crises of the past--from Lincoln and habeas corpus to Nixon and Watergate--Fein compellingly and presciently begins to answer those questions.
