When Professor Paul Kengor was on Sean Hannity’s radio show and later on Bill O’Reilly’s Fox News program, the hosts went out of their way to make sure that the author of the new book, The Communist, about Barack Obama’s mentor, was not saying that Obama himself was a communist. It was almost as if Kengor had been warned not to get too personal with his revelations. He was allowed to talk about Frank Marshall Davis being a communist who loved Joseph Stalin, but when the subject turned to Obama, who was under Davis’s influence for eight years, it was clear that this was another and more sensitive matter. This was getting dangerously close to taboo territory.
