I did your homework for you:
Analyzed Congressional Budget Office reports going back almost a decade, with the aim of understanding how the federal government came to be far deeper in debt than it has been since the years just after World War II:
You can think of that roughly $2 trillion swing as coming from four broad categories: the business cycle, President George W. Bush’s policies, policies from the Bush years that are scheduled to expire but that Mr. Obama has chosen to extend, and new policies proposed by Mr. Obama.
The first category — the business cycle — accounts for 37 percent of the $2 trillion swing.
About 33 percent of the swing stems from new legislation signed by Mr. Bush. That legislation, like his tax cuts and the Medicare prescription drug benefit, not only continue to cost the government but have also increased interest payments on the national debt.
Mr. Obama’s main contribution to the deficit is his extension of several Bush policies, like the Iraq war and tax cuts for households making less than $250,000. Such policies — together with the Wall Street bailout, which was signed by Mr. Bush and supported by Mr. Obama — account for 20 percent of the swing.
About 7 percent comes from the stimulus bill that Mr. Obama signed in February. And only 3 percent comes from Mr. Obama’s agenda on health care, education, energy and other areas.
37% Business
53% G.W. Bush
10% Obama
Obama's biggest mistake at creating dept was continuing Bush's policies.
