Writing political books is difficult these days. Events move so swiftly your work can seem irrelevant before it even gets to the copy-editing phase. [Aren’t you writing a political book?-ed. No, it’s a memoir with political overtones. Get that straight. You’re the editor — or one of them!] But the new work by Nancy Soderberg — The Superpower Myth: The Use and Misuse American Might — might take the cake for “dead on arrival.” Talk about the ghost of Jacques Derrida… this book seems almost an unconscious effort to drive people away from the Democratic Party.
