It now appears about 25 percent of Americans will hold Obama and the Democrats responsible, and only about 65 percent of will blame Republicans (with good odds that the other 10 percent will follow suit).

This is the reality with which Boehner must deal. The Republican Party’s reputation isn’t good; the reputation of Congress is even worse. Meanwhile, the president’s approval rating is up to 56 percent in Gallup, his highest level since 2009.

So Boehner put forward a proposal on which Republicans could vote so that the argument couldn’t be made that they didn’t act in the face of this looming catastrophe. But enough of his own members wouldn’t deliver the votes that he had to pull the bill.

The speaker’s doing what little he can with what little he has. Those conservatives who attack him for a sincere effort to manage an unavoidable defeat, or who are trying to raise money by using Boehner as a foil, are making an implicit case for their own marginalization.
