You can listen here.
My take: McDonald--with "a self-ordained professor's tongue too serious to fool" (to borrow from B. Dylan)--reveals a deep loathing for those who do not share her cultural proclivity for academic pedigree, pontifical articulation, and self-congratulatory verbosity. She is, sadly, not alone among the hob nob right snobs. She is joined by the linguistically adept David Brooks, David Frum, Chris Buckley, and Kathleen Parker. They, of course, like George Barnard Shaw, Aldous Huxley, and Margaret Sanger, write well, think big thoughts, and attend all the right parties.
To clip and paste from a famous line offered by Chris Buckley's late father, Bill: I would rather be governed by the first 500 names in the Wasilla, Alaska phone book than the guest list for a party at Sally Quinn's house.
Apparently, sometimes the apple does fall far from the tree.
