According to Jeffrey Anderson at Investor's Business Daily:
"In all, if Congress approves his current budget, Obama's deficit spending will total $3.5 trillion for the first half of his first term. President Bush's deficit spending totaled $2.9 trillion. In other words, Obama's deficit spending for his first two years in office will exceed Bush's deficit spending for his entire eight-year presidency."
