Tricks with Numbers.

Pirated & Paraphrased from the Internets:

Obama's 2013 budget includes $848 billion in savings from winding down the wars in Iraq and Afghanistan -- even though the administration had long made clear those wars would end. The Bush administration never properly accounted for war spending, refusing to project costs in the future, which kept its deficit projections artificially low. Now that the wars are winding down, the Obama administration is happy to project costs far into the future, because it artificially inflates the potential deficit reduction.
