Wait a minute. This graph is misleading. Last time I checked Obama took office in Jan 2009. It is true that the end of Bush II began the trillion dollar deficits. But Obama has continued that high level of spending for his 4 years in office. So maybe he hasn’t increased them, but he hasn’t reduced them either. If one were to do a bar graph of presidents running budget deficits, then Obama would take the cake.
The point of the graph is that even though each president spends more than the one before it, Obama had the lowest increase (as a percentage) over the spending of the president before him.
For example, if Clinton killed 5000 foreign civilians, and Bush II killed 50,000, and Obama kills 100,000 (the coming Iran war), Obama would still be less bloodthirsty than Bush because he only killed 200% more than the president before him instead of 500% more.
