Reddit reviews Nonbeliever Nation: The Rise of Secular Americans

Link to his book online, which I just now purchased: http://www.amazon.com/Nonbeliever-Nation-Rise-Secular-Americans/dp/023033895X/ref=sr_1_1?ie=UTF8&qid=1343844551&sr=8-1&keywords=david+niose

This book is a great source for answering your question: http://www.amazon.com/Nonbeliever-Nation-Rise-Secular-Americans/dp/023033895X

Criticism justified. Well, if the OP is going to be too simple-minded to do that, then I will:

• Amazon link
  
• A review in Publisher's Weekly - I didn't see an author's name.
  
• A discussion in Psychology Today
  
• A teaser for the book by the Friendly Atheist
  

Campquest's answer is spot on. But for a whole book about not only what this has to do with atheism but the place of rationality in American political discourse in general I highly recommend Nonbeliever Nation by David Niose.
