John Edwards Cameo at PDF

One of the highlights of PDF was when Elizabeth Edwards spoke to the crowd via Skype - she was supposed to attend in person but her flight was cancelled. And at the end of her Q&A, John Edwards came home and answered a two-part question for the PDF attendees about the Internet and how it has affected campaigning in general and the '08 election specifically. He gave a great answer, shown on this ABC News video.
