However, since I see these things coming up all the time, and there doesn't seem to be any great movement against them, I'm going to attempt an intelligent response.
First, as said already below, this graph compares eight years of the Bush administration to three years of the Obama administration "projected" into 2017. To anyone familiar with Washington projections, not only are they usually embarrassingly inaccurate, but they are also based on rosy assumptions. See the recent healthcare projections as an example: I don't have enough time to go into detail, but because of the way the CBO operates, their forecasts are constrained by what is actually in the bill versus what they think will happen. Simply put, if the bill says that it will reduce the deficit, then they have to put those assumptions into their forecast even if they don't think that it will come to pass.
Second, the graph seems to ignore the fact that Obama is not powerless in the face of Bush spending priorities.
A couple of examples: True, Bush started the wars in Iraq and Afghanistan. However, the "surge" in Afghanistan was all Obama's idea, and it was also his idea to keep troops in Iraq for several years into his first term.
Also, the "Bush" tax cuts are essentially now the "Bush-Obama" tax cuts, because as of recently, the bill has Obama's ink all over it. He certainly didn't veto the renewal of the tax cuts.
Third, the Obama graph does not include all of the additional spending that he wanted but did not get (high-speed rail, more infrastructure, green energy, student loans, etc.), including his most recent request of almost half $1 trillion of stimulus.
I would not disagree that we have a spending problem, but this graph does not contribute to any meaningful discussion of a solution.
Also, since everyone knows that Ezra Klein is at best left-leaning, please allow me to link to a equally right-leaning opinion on the same matter:
