I can only reiterate what others have said. This is not a book for Democrats on how to retool their message; it's a book on how to generate innovation and stay close to the base. I highly recommend it.
I'm now starting a book on the oil conflict in the Niger Delta, called "The Next Gulf". (Yes, I shamelessly pirated the title for a recent blog post.) It's currently only available in the UK. So far, it's a great read, and indispensible for an outsider to Nigeria, such as myself. The book is convincing me that every problem in Nigeria ultimately comes down to oil and the (mal-)distribution of the wealth it brings to the various parts and classes of Nigerian society.
