Actually it’s just north of $5 trillion. CNS provides the gory details:

(CNSNews.com)- In the 39 months since Barack Obama took the oath of office as  president of the United States, the federal government’s debt has  increased by $5,027,761,476,484.56.

Although he has served less than a term, Obama is now the first American president to see the federal government’s debt increase by more than $5 trillion during his time in office.

During the full eight years that George W. Bush served as president, the federal government’s debt increased by $4,899,100,310,608.44. (Rising from $5,727,776,738,304.64 to $10,626,877,048,913.08.)

The $5,027,761,476,484.56 that the debt has increased during Obama’s presidency equals $16,043.39 for every one of the 313,385,295 people the Census Bureau now estimates live in the United States.

At the close of business on Jan. 20, 2009, the day Obama was  inaugurated, the federal government’s debt was $10,626,877,048,913.08,  according to the U.S. Treasury. By the close of business on April 16,  2012—as many Americans were working to finalize their 2011 tax returns  to meet an April 17 filing deadline—the debt had reached  $15,654,638,525,397.64.

The $5,027,761,476,484.56 in additional debt that the U.S. government  has taken on during the 39 months that Obama has been president is more  debt than the federal government accumulated in the first 219 years of  the Republic.

More here. But not to worry folks.  As I noted yesterday, the effete David Brooks is convinced of Obama’s commitment to “fiscal sustainability”:

I’ll just say that my conversations reaffirm my conviction that Obama is a pragmatic liberal who cares about fiscal sustainability…

One would think that with Obama spending us into bankruptcy and his regime speeding individual Americans down Hayek’s Road to Serfdom, the upcoming election would be about big things.  You’d be wrong, of course.  I wish I could be optimistic, but given the choices in this year’s election, I’m not.
