Case in point. That's just not true. Bush started two illegal foreign wars that ultimately added up to a cost of over a trillion dollars. That alone dwarfs much of what Obama has done. And the big supposed drain on the deficit, the Affordable Care Act/Obamacare, actually reduces the deficit due to tax increases used to pay for some of its expenditures. Obama is guilty of a lot of things economically (he's basically a moderate Republican in terms of actual policy), but acting as if Bush (or even Romney, or any other recent Republican candidate for that matter) would've done any different is just not true.
Obama plays hardball and keeps just fucking burying us and piling on more debt faster than anyone in history...by far
