We are not having a debt crisis.
No, what we’re having is a political crisis, born of the fact that one of our two great political parties has reached the end of a 30-year road. The modern Republican Party’s grand, radical agenda lies in ruins — but the party doesn’t know how to deal with that failure, and it retains enough power to do immense damage as it strikes out in frustration.
Since the 1970s, the Republican Party has fallen increasingly under the influence of radical ideologues, whose goal is nothing less than the elimination of the welfare state — that is, the whole legacy of the New Deal and the Great Society. From the beginning, however, these ideologues have had a big problem: The programs they want to kill are very popular. Americans may nod their heads when you attack big government in the abstract, but they strongly support Social Security, Medicare, and even Medicaid.
And look at where we are now in terms of the welfare state: far from killing it, Republicans now have to watch as Mr. Obama implements the biggest expansion of social insurance since the creation of Medicare.
So Republicans have suffered more than an election defeat, they’ve seen the collapse of a decades-long project. And with their grandiose goals now out of reach, they literally have no idea what they want — hence their inability to make specific demands.
It’s a dangerous situation. The G.O.P. is lost and rudderless, bitter and angry, but it still controls the House and, therefore, retains the ability to do a lot of harm, as it lashes out in the death throes of the conservative dream.
