When reflecting on what a frighteningly-bad President George W. Bush was, I still recall this Onion article from January 2001. You should read this, bearing firmly in mind that it was written before W. was inaugurated, and was intended as alarmist hyperbole. What follows is a fairly-straightforward summary of the 8 years that followed.
Lest we forget, we complacently tolerated 8 years of pious incompetence, relying on sound bytes and circular reasoning while W. squandered every advantage left to him by the Clinton Administration. On almost any dimension you choose to compare January 2001 to January 2009, the reversals of this failed Presidency look absurd.
