To clarify, opinions are fine if the reasoning for the opinion is provided -- in which case one is providing a reasoned conclusion rather than a mere opinion. For example, while it may be your opinion that center left think tanks only produce lies or inaccurate information, your opinion alone does not qualify as debate (in fact, logical fallacies such as that will lose you points in a formal debate).
'Because I say so' is not an argument. At least not beyond, say, age 8debate
formal, oral confrontation between two individuals, teams, or groups who present arguments to support opposing sides of a question, generally according to a set form or procedure

Given that you want to assign only about $400B of the FY2008 shortfall to Bush and/or Bush policies, while given that we know that at least the wars were being run off budget (which would increase the $400B by a significant amount), let's try a different approach -- one not susceptible to opinions, interpretations, or budgetary smoke-and-mirrors, although we will have to abandon the FY approach:
On 1/22/2008, the total public debt, as it is currently defined, was $9.2 trillion
On 1/20/2009, when Obama took office, the total public debt was 10.6 trillion ( Government - Debt to the Penny (Daily History Search Application) )
Clearly, during Bush's last year in office the effective annual deficit was $1.4 trillion. No smoke. No mirrors.
Karl, you are a total bloody hypocrit on most of the content of your post so be careful you dont fall off that high horse, you may hurt yourself. Stick to the topic and dont assume an arrogant lecturing posture, you dont have the balls or the brains to pull it off with aplomb.
