Little news of progress from the Joint Select Committee on Deficit Reduction probably means one of two things: Either the “supercommittee” is good at keeping secrets, or it’s not making much progress.

Defense clearly takes the biggest hit. One point made clear here, but rarely discussed, is that lower spending on interest plays a relatively significant role. Sixteen percent of the savings, or $169 billion, comes from the United States paying less interest on its presumably smaller level of debt. The savings from lower interest spending are projected to be even higher than those from Medicare, where cuts are capped at 2 percent of the program.
