Ezra, who understands such things, thinks that the GOP might skip shutting the government down through budget buffoonery so they can take another shot at the debt ceiling. A red doomsday button does grant some extra negotiating leverage, if you can convince the other guy that you really are bugfuck crazy.
This raises a question that has stuck with me since the last debt ceiling crisis. As I understand it the last compromise did not lift the debt ceiling but rather set back the date when the government would have to deal with it. The annoying but not-end-of-the-world result of this decision would be that Congress has to raise the debt ceiling by some amount more than it otherwise would have done. That makes it harder to get the Congressional Branch Davidian caucus on board but no biggie since Boehner seems to have misplaced the stone tablets on which they etched the Hastert Rule. On the other hand, it might be a good idea for someone to check whether this makes the the Cantor Gambit a bit more risky, this being the negotiating ploy where Congress lets the formal deadline lapse and counts on creative bean counters at Treasury and Fed to save us all from certain doom. If Cantor tries his gambit this time, would the extra back-pressured debt make it harder for the bean counters to keep armageddon at bay?
Just thinking out loud here. No need to panic since I am sure the GOP understands what they are doing and have every intention of negotiating in good faith.
