Okay, let's ignore the whole issue of misleading the country into an unarguably immoral war. Moby, over at one of my favorite Blogs, suggests the following:
In the last year of Bill Clinton's presidency, the United States had a budget surplus of $127 billion dollars. When George Bush was elected, he promised a budget surplus of $262 billion dollars by 2004. On friday, the Bush administration presented a budget that has the largest deficit in the history of the United States: $445 billion dollars. So, in three years, the Bush administration have taken a $127 billion dollar surplus and turned it into a $445 billion dollar deficit.
That's a difference/loss of $572 billion dollars.
