Michael Knox Beran is an author and columnist whose work I respect. He writes for conservative publications, like National Review and City Journal. His book on RFK, The Last Patrician: Bobby Kennedy and the End of American Aristocracy, is well-worth a read for the theory he has as to what drove the man to do what he did, although I don't buy all of it, but it did provide me with a better understanding of the man.
A most excellent article by our friend Bob. As he says, fix yourself a tall drink before sitting down to read this one.
