Based on a very good recommendation, I have just finished a biography on the Mitford Sisters. One sister was often identified as Hitler's girlfriend, Unity Mitford; another married the UK Fascist party head Oswald Mosley, Diana Mosley; another became a committed Communist and moved to the U.S. where she became an investigative journalist and author, Jessica Treuhaft; the eldest became a noted author and employed at the bookshop around the corner from us, Nancy Mitford; and another became (and still is) the Duchess of Devonshire, Deborah Cavendish.
Unity had introduced Diana to Hitler, and Diana pursued a friendship with Hitler to acquire a radio broadcasting license to fund the fascist activities of her husband. Hitler became her great admirer, and the two would often talk after Hitler's long days about politics, art, culture, and the like. Diana also knew well her cousin Winston S. Churchill, who attempted to alleviate Diana's suffering while imprisoned in London during WWII. Diana was thus said to have been possibly the only individual to have known Hitler and Churchill well. Some have speculated about what would have happened (or not happened) had Diana (or Unity) been able to introduce the two men as was attempted on more than one occasion.
In any event, I thought of Diana's unique position yesterday when I read this article about Harry Reid lambasting Mitt Romney. Should Mitt win the Repulican nomination and presidency, based on the unique geographical orientation of LDS congregations, the president and the Senate Majority Leader would worship in the same congregation, call each other "Brother Reid" and "Brother Romney," and be in the same men's group, working and serving the congregation together. (John Huntsman has already moved into that congregation, so I hear.) Instead of a person bringing them together, church service would. I'm sure ideological differences would persist, but I do wonder whether political "wars" and stalemates would be avoided should they come to know each other on a personal level.
