David Brooks' tantrum apparently got a lot of facts wrong – see Timothy Noah on tax rates and Greg Sargent on tax increase popularity. But no post will beat Jonathan Cohn's parody for entertainment value:

With this column, Brooks has decided to write about politics as a conventional conservative pundit. I guess I understand the choice, but I still believe he can do better. I think he has a genuinely open mind and an utterly commendable commitment to civility. And I think those things are compatible with reasonable, if still (by my lights) overly conservative, arguments. I know. I may be the last one. I'm a sap.
