From the American Prospect:
Although some reviewers have inexplicably branded the books "monoculturalistic" and even "sexist," Rowling has admitted to being "left wing" personally and hoped that "every reader will bring his own agenda to the book." Rowling has an enormous audience -- and probably more U.S. supporters than any one of the current Democratic presidential hopefuls. With 9.3 million copies of the book making their way into Americans' hands, it's worth asking: Does Harry Potter have liberal leanings?
