Your statement lacks meaning, as it fails to take into account inflation, or the relative size of the debt to GDP over the years.
Also, virtually all new debt incurred was a result of the wildly irresponsible policies of the previous Bush administration, or in some cases previous administrations that had had fostered deregulation over the years. Two ill advised wars, an unaffordable tax giveaway to the rich, and the cumulative effects of freeing up the baser instincts of Wall Street led to a near meltdown in the world economy. All this was dumped into the lap of the hapless winner of the '08 election. The fact that, only a few years later, the far right feels it can attempt to blame the current administration for the problems they themselves caused is not only an extreme example of what the Jews call "chutzpah", but an insult to the intelligence of thinking people.
