Read Adam Smith's “Theory of Moral Sentiments”!
A work that he thought was more important then “Wealth Of Nations”. I would say a knowledge of Smith is incomplete if one only reads “Wealth of Nations”. They must be read together as a set to understand the points Smith makes in both books.
Read these then judge Newt & Romney!
People forget that Smith was a moral philosopher, and that for him, the term political economy had a special meaning.
