I've heard him speak to this on numerous occasions. He says the Declaration of Independence answers the "why" question and the Consitution answers the "how" to accomplish what was laid out in the Declaration. Without BOTH, the meaning gets lost.
If I understand him correctly, this is what Mark Levin maintains. Frankly, I don’t see how it can be any other way. IMO, this is one of the areas where libertarians get it wrong. It seems that it never occurs to them that these two documents must be taken as a unit, and the Declaration is the document they want to forget.
One of the things I admire about Santorum is that he gives not only a plan, but also the philosphical and Constitutional reasons for the plan, and why the plan will work. He gives so much more than the usual candidate. I find his talks exciting because his message is congruent with America’s foundation, which resonates in our own time in the spirit of Reagan.
We don need no stinkin purity test! Conservatives can quickly recognize what Santorum is offering. So many people are not used to seeing the face of a joyful man who presents himself, as well as his faith and thought, to the world “without wax.”
