Sorry for the small font on this -- the table is from here if you want to see original. I added the last line, percent growth year on year.
Three main points to note: First, the 18% increase in total federal outlays from 2008 to 2009, on top of a 9% increase 2007 to 2008, both of which were stimulus to a great extent. Second, since then, there is only one year when nominal spending went down, by 2% from 2009 to 2010. And third, overall between 2007 and 2012, nominal Federal outlays are up 39%.
In previous posts, I noted my fear that stimulus spending would become permanent. Here is a quick graph of the outlays from 2007-12.
