The differences between Obama and Bush are multiple as they are fundamental. Obama would never have gone to war in Iraq. Obama would have wound down the U.S. presence in Afghanistan years earlier. Obama would have engineered a better response to the financial meltdown in 2008 than Bush's man Henry Paulson directed. Yes, Obama has been a disappointment, but please don't confuse the two. They are galaxies apart and forced to work within the limitations of a gridlocked American political system.
