"We need a system for deciding who gets in and who does not. That's not cruel, it's just rational."

Meet Ruy Teixeira, political demographer, commentator and author of the deeply influential 2002 book "The Emerging Democratic Majority" with co-author John B. Judis. Today, he has a new book out: "Where have all the Democrats gone?" with the same co-author, and a very different message.

We get into it in this conversation.
