This video of Clay Shirky (bio below vid) is good since the man lives in a technological world that most people over 50 do not participate in. The interesting bit about how a new political party could evolve in the US is around 15 minutes into the vid. That is not to say the first 15 minutes is not worth watching.
Guys and Girls - I recommend watching this. We are already part-way there and you might as well get on the train or at least know how to buy a ticket and board when you need to make the trip.
or, if that link does not work watch it in three parts on youtube...
