Whatever George W. Bush did or did not do, he’s no longer in office, and doesn’t have the power to do a damn thing about the budget. Obama is the one who is president with the really humongous deficits. Deficits of the size Bush ran are basically sustainable indefinitely; deficits of the size that Obama is apparently planning to run, aren’t. If he doesn’t change those plans, he will be the one who led the government into fiscal crisis, even if changing them would be [sob!] politically difficult.
I have a serious question for the people who are mounting this defense: at what point in his presidency is Obama actually responsible for any bad thing that happens? Two years? Five? Can we pick a date for when bad things that happen on Obama’s are actually in some measure the responsibility of one Barack Obama, rather than his long gone predecessor? And then stick with that date? Conversely, can we agree that as long as the bad things that happen are really George Bush’s fault, any good things that happen should probably be chalked up to his administration as well?
