My question is whether Jim Demint wants a default. There has been rhetoric wafting around the Tea Party for awhile now indicating an affirmative desire to engineer a default as a part of a strategy to permanently shrink the government. If he does, and if he starts whipping the conference through Cruz and the other like-minded Tea Party guys, Boehner and the other "moderates" are weak enough that they might just roll over like they always roll over.
That is an interesting idea that I have not yet considered. They want a default so that it forces the shrinking of government. If we are no longer the world reserve currency, that will dramatically reduce our ability to refinance our debt at such artificially low treasury rates. Rates rising to 5% would explode our interest payments and crowd out a lot of other discretionary spending.
At the end of the day, I don't think either party wants a default. A few people might be less concerned than others (Demint, Bachmann).
But it is also fairly obvious that reforms to entitlements have to come. Everyone agrees on that issue. In the absence of a deadline on "must pass" legislation, I don't see any progress being made on any spending or entitlements. There is no pressure to negotiate without a deadline and horrible consequences.
