With the debt we've run up (and continue to expand) combined with the clowns running things in DC it's a wonder our government debt isn't rated on par with junk bonds.

EDIT: I find it humorous that people are taking offense and down-voting my comment as though I was referring to only a subset of the people in DC as clowns. We've been running a deficit annually since the early 80s (with one anomalous year in the 90s) and the fact we've not had blow-back in the credit markets is astounding. This is only possible when we enforce the petro-dollar system with the might of the US military, something the rest of the world has grown weary of. Once we lose reserve currency status our gov't debt will indeed slide to junk status and right quick.
