'Pennsylvania Avenue'; Jonathan Zittrain

John Harwood from The New York Times and Gerald Seib from The Wall Street Journal examine the presidential campaign in their book, "Pennsylvania Avenue: Profiles in Backroom Power." Jonathan Zittrain, professor of internet governance and regulation at Oxford University, discusses the lack of security on the internet and how it stifles innovation, as he does in his book,"The Future of the Internet and How to Stop It."
