According to the Congressional Budget  Office, Obama’s proposed budget would add over $9.7 trillion to the  national debt over the next ten yeas. They made the announcement on  Friday, and claim that the President’s tax cuts for the middle class  are the main reason for the shortfall.
The 10-year outlook released by the nonpartisan  Congressional Budget Office is somewhat gloomier than White House projections,  which found that Obama's budget request would produce deficits that  would add about $8.5 trillion to the national debt by 2020.
 
The CBO and the White House are in relative  agreement about the short-term budget picture, with both predicting  a deficit of about $1.5 trillion this year -- a post-World War II record  at 10.3 percent of the overall economy -- and $1.3 trillion in 2011.  But the CBO is considerably less optimistic about future years, predicting  that deficits would never fall below 4 percent of the economy under  Obama's policies and would begin to grow rapidly after 2015.
 
Deficits of that magnitude would force  the Treasury to continue borrowing at prodigious rates, sending the  national debt soaring to 90 percent of the economy by 2020, the CBO  said. Interest payments on the debt would also skyrocket by $800 billion  over the same period.
