Consider that just two pieces of legislation he signed account for nearly a third of the $5.2 trillion in deficits since 2009:

The American Recovery and Reinvestment Act of 2009, better known as the stimulus act, will cost $831 billion through 2019, according to the CBO. The administration estimates the stimulus at $800 billion through 2011.

The Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 extended the Bush tax cuts and cut the Social Security payroll tax for two years, as well as provided relief to some taxpayers who otherwise would have had to pay the alternative minimum tax. The 2010 tax act cost nearly $800 billion in 2011 and 2012.

The administration does not take responsibility for all of the spending in the 2010 tax act (which we will detail later). But Treasury accepts that the administration is responsible for another $410 billion in additional tax cuts and spending through 2011.

That means at a minimum the Obama administration is responsible for $2 trillion, or 39 percent of the $5.17 trillion in deficits since fiscal year 2009.
