Goodbye and good riddance.
On a personal note, my loss of employment, and growing atrophy of whatever social skills I have left.
On a broader scale, the entire Bush the Lesser era should be viewed by historians as one of the greatest debacles - two quagmire wars, prolific spending and massive deficits, cultural warfare, an entire political/media culture without accountability - in American history. Forget any nostalgic feeling for the 1970s, of which there are actually few (Star Wars, the advent of punk). The 2000s were horrifying.
See ya all in 2010.
