Lets try the math again, Bush increased the debt about 5 trillion to a total of 10 trillion in debt when Obama took office. Debt is now 21 trillion. 10 trillion to 21 trillion is an increase  of about 11 trillion. With a year still to go, I am just glad that republicans are in control of the house and senate. If they do their job, we might see a very low deficit this year, and only a small increase in the debt. Obama should be very happy with the republicans for keeping the increase of the debt to under 12 trillion under his administration.
