As the shouting persisted, it became clear that the government of the most powerful country in the world was being held hostage by a band of fanatics who (1) represent a very small proportion of our population; (2) hate government so much that they relished the idea of closing its doors, no matter the cost; and (3) have neither respect nor patience for the normal democratic give-and-take between competing parties and points of view.

In no serious country do threats to shut down the government become a routine way of doing business. Yet in our repertoire of dysfunction, we are on the verge of adding shutdown abuse to abuse of the filibuster in the Senate…

In those Tea Party shouts of “Shut it down,” the “it” drips with contempt. We cheer when drug dens or terrorist havens are shut down. There should be no glee over shutting down our government. Threatening the functioning of the public sphere is not an acceptable tactic in a democracy.

For Obama, it is not good enough to cast himself as the school principal scolding competing congressional gangs. He needs the courage to defend the government he leads.
