CBO: Budget Outlook 2010
"CBO projects, that if current laws and policies remained unchanged, the federal budget would show a deficit of $1.3 trillion for fiscal year 2010. At 9.2 percent of gross domestic product (GDP), that deficit would be slightly smaller than the shortfall of 9.9 percent of GDP ($1.4 trillion) posted in 2009. Last year's deficit was the largest as a share of GDP since the end of World War II, and the deficit expected for 2010 would be the second largest. Moreover, if legislation is enacted in the next several months that either boosts spending or reduces revenues, the 2010 deficit could equal or exceed last year's shortfall."
