We are not having a debt crisis.

It’s important to make this point, because I keep seeing articles about the “fiscal cliff” that do, in fact, describe it — often in the headline — as a debt crisis. But it isn’t. The U.S. government is having no trouble borrowing to cover its deficit. In fact, its borrowing costs are near historic lows. And even the confrontation over the debt ceiling that looms a few months from now if we do somehow manage to avoid going over the fiscal cliff isn’t really about debt.

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.

Before I talk about that reality, a word about the current state of budget “negotiations.”

Why the scare quotes? Because these aren’t normal negotiations in which each side presents specific proposals, and horse-trading proceeds until the two sides converge. By all accounts, Republicans have, so far, offered almost no specifics. They claim that they’re willing to raise $800 billion in revenue by closing loopholes, but they refuse to specify which loopholes they would close; they are demanding large cuts in spending, but the specific cuts they have been willing to lay out wouldn’t come close to delivering the savings they demand.

It’s a very peculiar situation. In effect, Republicans are saying to President Obama, “Come up with something that will make us happy.” He is, understandably, not willing to play that game. And so the talks are stuck.
