He notes that when pundits talk about “the center”, they are endorsing a radical agenda that is overwhelmingly opposed outside the beltway:

Martin’s article doesn’t define “the center.” But it’s not the center of public opinion. It’s more a reference to an amorphous Washington consensus. Insofar as that concept ever made sense, the idea was that it’s the legislative center, the zone of compromise where things can actually get done. But even that concept has begun to break down in recent years, as that Washington center — what you might call the “Simpson-Bowles center” — no longer holds any weight in Congress.

When you’re judging policy, “good” and “bad” are descriptions that make sense. So are “popular” and “unpopular,” and “likely to pass” and “no chance.” But “the center”? It’s time to retire that one, or at least come up with a more rigorous definition of what we mean when we use it.
