Fun with numbers.
Why 2001? We didn't invade Iraq until March of '03?
Of the 787 billion you noted, just over 400 billion has been spent since last month.
On top of that, 288 billion of the stimulus was in the form of tax cuts.
^Anyone who uses the term "tax expenditure" should never be allowed within five hundred miles of a political office^
So is a tax cut an expenditure or not?
