Through all of fiscal 2008, before Obama took office, the federal government spent a total 2,978,440,000,000.00. Adjusted for inflation, that equals $3,211,717,910,000.00 in 2013 dollars. So, were the government to continue on its pace to spend $3,610,912,800,000.00 this year, then real federal spending in fiscal 2013 would be $399,194,890,000.00 more than it was in the last full fiscal year before Obama became president.
Congress would need to cut $399 billion this year to bring inflation-adjusted federal spending back to the level it was before Obama.
According to the CBO, the sequester that has now taken effect will cut only $44 billion from the money that was expected to be spent through the remainder of this fiscal year.
