Slate:

Despite all the talk from politicians about "out of control" federal debt, the truth is that by almost any sensible measure the federal government isn't borrowing enough money. Consider Bloomberg's report that total debt in the United States "has shrunk to a six-year low relative to the size of the economy as homeowners, cities and companies cut borrowing, undermining rating companies’ downgrading of the nation’s credit rating."
Americans are actually tightening their belts, borrowing less, and this is not good for the current system. In such a situation, to keep the economy running (which only means: keep the economy growing—growing and running are, sadly/politically, the same thing), the government has to do the borrowing. But it's not. Borrowing is actually at a 6-year low. The GOP will not point this out (Obama is not really borrowing), and a good guess is that they are probably responsible for this economy-hurting low (they will not let Obama borrow because that would help him politically). We can be sure that the borrowing will resume if Rmoney is elected.
