Jonathan Chait:

Bipartisan agreement is not necessary to fix the debt. Nothing is necessary to fix the debt. It is as if the network of activists, wonks, business leaders, and Beltway elder statesmen who have devoted themselves to building cross-party support for a deficit deal have grown more attached to the means of bipartisanship than to the ends for which it was intended. The budget deficit is a legislatively solved problem. It is, indeed, an oversolved problem. In the absence of any agreement between the president and Congress, the deficit will shrink to less than one percent of the economy by 2018, and remain below that level through 2022. The budget deficit declines so sharply and so drastically, and in ways that neither party is entirely comfortable with, that the task for Washington is to pull back on deficit reduction.
