But it is the middle two paragraphs of the post, where he goes after the actual ideology, should be required reading for anyone who would call themselves a liberal:
Krugman makes two crucial points here. The first is how could anyone with three functional brain cells have ever found anything compelling, let alone admirable, in the political ideology of the Movement Conservatives? They were as incoherent and intellectually compromised in 1994 as they were in 2004. There is nothing here that should be treated with anything except derision should it dare show its face in public.
... And yet — why, exactly, should we listen to people who by their own admission completely missed the story? I mean, anyone who actually listened to what Newt Gingrich and Dick Armey were saying in 1994, let alone what passed for thought in the Bush administration, should have realized long ago that if there ever was an intellectual basis for modern conservatism, it was long gone.
And the truth is that the Reaganauts were a pretty grotesque bunch too. Look for the golden age of conservative intellectualism in America, and you keep going back, and back, and back — and eventually you run up against William Buckley in the 1950s declaring that blacks weren’t advanced enough to vote, and that Franco was the savior of Spanish civilization.
The second point is the more telling. No matter how far you go back in the Movement Conservative history, you cannot find anything that is not poisonous. The founder of this ideological nightmare, William Buckley, used racism and fascism as foundations for his shining city on a hill. 1994, 1984, 1980 and the Gipper himself; it doesn't matter where you try to locate the golden era of this creed, Movement Conservatism has always already been allied with the worst impulses of the nation.
The third point he leaves as a lesson for the reader to draw - And just why does anyone on the Left feel a need to compromise with this most compromised intellectual agenda? How can anyone with the conscience of a liberal express any admiration for a faction that is rooted in socio-political commitments antagonistic to the rule of law and the fundamental premise of human equality?
