Interesting ideas. I would imagine Cass Sunstein will likely appear on The Daily Show to hawk his book within the next few weeks. But for now, if you are in the DC area, he'll be launching the book and hosting a discussion at the Brookings Institution tomorrow/Friday the 5th, which I assume will eventually show up as a podcast, as many brookings panel discussions do.
The podcast of the talk and discussion has been posted on the page linked to here. If you're looking for an intriguing talk to listen to on your morning commute, give it a whirl. Some interesting folks in the audience asking questions.
