It’s a libertarian one, too, of course:
Marriage is not an issue that people rationalize through the abstract lens of the law; rather it is something understood emotionally through one’s own experience with family, neighbors, and friends. The party of Lincoln should stand with our best tradition of equality and support full civil marriage for all Americans.
This is both the right thing to do and will better allow us to confront the real choice our country is facing: a choice between the Founders’ vision of a limited government that empowers free markets, with a level playing field giving opportunity to all, and a world of crony capitalism and rent-seeking by the most powerful economic interests.
Adam Smith was not only an architect of the modern world of extraordinary economic opportunity, he was a moralist whose first book was The Theory of Moral Sentiments. The foundation of his thought was his insight that free markets and open commerce strengthened our moral fiber by reinforcing the community of shared and reciprocal economic interests. Government, he thought, had to be limited lest it be captured and corrupted by special business interests who wanted protection from competition and the reciprocal requirements of community.
