Rick Santorum has an excellent book out called It Takes a Family: Conservatism and the Common Good. While many of us have grown up with an intuitive understanding of the importance of conservative principles, I think Rick Santorum has done a fabulous job of making the intellectual case for it in terms of living in community for the common good. I'm not finished with it yet, but this book is awesome.
