I haven't read this book but am aware of its premise.
Does the book offer the reason for what the Bush Presidency has done? Bush/Cheney are only in office a max of 8 years. Once they leave, the additional powers afforded the President is no longer accessible to them personally.
To me, Bush/Cheney and their cronies used the Presidency to further their own financial gain (an obsence use of the Presidency and the concept of a government of, by, and for the people) . And possibly to advance the one world government that is spoken about so often in conspiracy oriented circles.
