Dean and Nader debate the role of third parties on NPR. Each excels at staying on message.
Nader hits his marks: no draft, end corporate greed, waste, fraud, etc, proportional representation. He wants "binding none of the above" as a choice on all ballots - which is, of course ridiculous (Dean's point on that: we live in a real world, we have to make real choices. Amen, Howie).
Dean his the most important mark:
We can't let the perfect become the enemy of the good.
