You and fact check made the same mistake that most calculators make: the budget that a new President implements is prepared by his predecessor. Thus, the FY 2009 budget was prepared by President Bush.

The only reliable source of debt figures is the US Treasury's Reports. As they illustrate, the national debt increased by $6.1 trillion from 10/02 through 9/09; it has increased $4.1 trillion from 10/09 through present.

Another common mistake is to forget (or not know) that the federal fiscal year differs from the calendar year and that it is only the US Congress that can pass laws and make appropriations. Thus, the accrual of national debt to Presidents is misleading, at best.
