we are running at a 35 to 40% clip of short term rollover on debt loads of 1T plus. And to be precise..that number is actually 60+%
If we were financing all of this on 30 yr notes maybe, but...
Of the marketable securities currently held by the public as of
September 30, 2010, $5,180 billion, or 61 percent, will mature within the next 4 years (see Figure 3)
5.2T of the debt will need to be refinanced within 4 years. (and thats only of the amount held by public, not intergovernmental...assuming the same ratio that only makes matters worse.

In addition, they're selling the TIPS stuff to the public which is adding inflation risk to the government on the cost of those securities.
So, a 4ish point rise in inflation..and the rise in rates to go with would drive short term debt service costs up about 200 to 250 billion per year.
In and of itself, maybe no big deal...but it does make any attempt to reign things in that much harder, doesn't it...if in addition to service cuts and everything else the debt commission is proposing..you pitch another quarter trillion on top of as increased interest expense.
