I love people that need lessons in how to read charts:

The nation prospered during the 1990s due to an explosion in technological efficiency creating a massive tech bubble combined with policies created by the Clinton led White House and Gingrich led Congress (I don't care who you want to give the majority of the credit to for that because to get what they got done done they both needed each other). You can see the effect of this by the declining deficit over this time period. One area where Clinton gained a lot in picking up ground on the deficit was by cutting defense spending ...
You'll see that the deficit started to pick up shortly after Dubya took office in January 2001 and that coincided with an uptick in military. There were two primary reasons for this. First, one of the main criticisms of what Clinton did with the military was that many viewed it as poorly equipped and inadequately prepared. Second, the impact of 9/11 hastened the need not only for what was the military action against terrorist networks that resulted, but also investment in military intelligence to protect against the modern terrorist threat. Additionally, for those that don't remember (and as a Senior at the UW at the time trying to find a job I'll never forget this), as soon as 9/11 happened, the job market dried up immediately. While the unemployment rate was slowly rising as Dubya inherited the office from Clinton, the big upticks came around the time of 9/11 going forward.

About midway through Dubya's first term as the economy turned around and success in Iraq/Afghanistan was evident, you'll find that the deficit and military spending once again decreased as economic prosperity once again became the rule of the day. The massive spike that you see is tied to the banking/housing bubble burst as well as the automotive industry falling on its face. How much of that you put the blame on Dubya (many of the policies that led to this were created during the Clinton Administration) is debatable. He clearly could have probably been more proactive. Could very easily accuse the Fed of being asleep at the wheel.
Obama had a number of issues early in his presidency. While he has brought down spending compared to what he inherited, the biggest issue many have with his spending is that at no point is he projecting to do anything other than get to as low as Dubya's highest points (excluding the '08 crashes). His spending is generally irresponsible and he's got absolutely no problem spending what he doesn't have. It's very hard to argue against that when you look at the graphs and projections.
