Now that the Republicans can see how much leverage the debt ceiling gives them, they’re going to pull this stunt every time it gets near. The best-case scenario, with a big $2 trillion increase, would mean that we’re going to go through the exact same thing late in 2012; a more modest increase in the debt limit would set up a reprise of the current fiasco much sooner.
And that’s the invidious thing about low-probability events. Repeat the experiment often enough, and eventually they’ll happen. We’ll get a deal done this time. But one day, we won’t. And that day is not going to be a happy one.
