Remember last week when Pat Buchanan, noted fighter of white male oppression, went on Rachel Maddow's show and launched into one of the more staggeringly imbecilic rants in the history of political punditry? Last night Maddow re-visited that whole episode.

It, Maddow's "corrections and clarifications," was a thing of beauty to watch, downright surgical in precision, even though it would have been all the more better if Maddow had booked "Uncle Pat" to sit in on the whole thing and look angry and miserable when he wasn't hurling hate speech laced with old man spittle. Oh well.
