Obama's huge increase in government spending

The graph makes it very easy to see when Obama became president.
If one is interested in total spending rather than percent of GDP, I have my piece from last week available here.

Here are the raw Federal government spending by year. Just look at the increase from 2008 to 2011.

2000 1,789.0
2001 1,862.8
2002 2,010.9
2003 2,159.9
2004 2,292.8
2005 2,472.0
2006 2,655.1
2007 2,728.7
2008 2,982.5
2009 3,517.7
2010 3,456.2
2011 3,818.8
