The Federal budget for 2009 was for the period October 2008 – September 2009.
Bush originally proposed a budget with a 400 billion deficit.
The Democrat controlled congress funded the government by continuing resolutions until Obama took office.
He signed, in private a budget that increased the deficit to 868 billion.
The Obama administration deceptively attempts to attribute this budget to Bush.
Obama has made the claim that under his administration the growth of the deficit is the lowest in decades.
He does this by not including the 2009 budget.
So he didn't inherit this mess from Bush. The Pelosi / Reid congress created it and he is the one that signed it.
They own it.
