Making reference to television programs of a bygone era is pretty silly and rather petty, but if Milbank's going to do so he really should make more apt comparisons. I'd liken Al Franken to Eddie Haskell and Judge Gorsuch to be more like Ward Cleaver. Franken's pretend intellectualism and fawning to those who act more adult like, but chiding of those he considers to have more power over him, like real adults, and derision to those he believes are beneath him is like the real Eddie Haskell. All the while Judge Gorsuch was able to demonstrate his intellect and knowledge of law and the canon of ethics to place, and quite ably so, Al Franken in a disadvantageous light. 
Milbank, your biases are showing and you can't back them up. Try looking at things with some objectivity. Using references to TV programing of 60 years ago is absurd.
