President Obama‘s budget, released Monday, was conceived as a blueprint for future spending, but it also paints the bleakest picture yet of the current fiscal year, which is on track for a record federal deficit and will see the government’s overall debt surpass the size of the total U.S. economy.

Mr. Obama‘s budget projects that 2011 will see the biggest one-year debt jump in history, or nearly $2 trillion, to reach $15.476 trillion by Sept. 30, the end of the fiscal year. That would be 102.6 percent of GDP — the first time since World War II that dubious figure has been reached.

And the budget projects the government will run a deficit of $1.645 trillion this year, topping 2009’s previous record by more than $230 billion. By contrast, 2007’s deficit was just $160 billion altogether.

Still, amid the other staggering numbers in the budget Mr. Obama sent to Congress on Monday, the debt stands out because Congress will need to vote to raise the debt limit later this year, and because the numbers are so large.
