The simplest answer or deconstruction of a question is often the least corrupted.
Bush added about $5 trillion to our debt in the course of 8 years.
While this amount is not exactly accurate given the GDP in 2000 versus 2008, the actual decrease in spending on most programs, and the nearly $1 trillion Bush spent in the intial bailout.
Mr. Obama has increased the national debt about $2 trillion since he took office.
