David Corn had hoped that Obama would get mad:

Obama has long eschewed the partisan rancor of Washington, and maintaining an above-the-fray status has often served his political interests. But he’s never going to run for president again—avoiding the angry-black-man trap is now not as important—and desperate times do demand reconsideration of assumptions and behavior. This could well be the moment in his presidency that demands a strategic flash of anger and/or derision. Obama ought to tell us how he really feels about the House Republicans willing to close the government or trigger a default in order to undo his signature domestic law. Whatever the political impact of such a statement, it would sure have the benefit of being the truth.
