The Constitution is important. ...
But the Constitution (like the Federalist Papers, and Declaration- and Founder-worship in general) has played a larger role in conservative rhetoric than a mere defense of the clear provisions of the document could do. Defense of the Constitution has become a rhetorical crutch. It has become a substitute for an agenda that is relevant to the issues of the day.
This is understandable. ...
Talking about health care policy (any health care policy) will also involve tradeoffs. It is much easier to talk about how, as president, you will protect the beloved Constitution, than to talk about how you will seek to change health coverage in the direction of catastrophic coverage (which will make some health insurance recipients nervous) and how you will seek to make it easier for new market entrants to disrupt existing providers (which will make existing heath care providers very cross). Better to mumble some things about tort reform and then go back to talking about the Founding.

If you make people choose between constitutionalism and their everyday concerns, the Constitution will lose.
I've met a number of conservatives over the last decade or so who were much more interested in discussing the issues of 1773, or 1803, or 1860, than they were the problems of the current day.
I'm absolutely not one of those people who think the Constitution is obsolete. It wasn't written for the times but for humanity, and humanity hasn't changed all that much. But the world does change, and if conservatives hope to influence the nation they'll have to address today's issues in ways consistent with the Constitution. And not just propose solutions, but convince a majority of Americans that those solutions will produce a better future for them than the alternatives.
But I think I'm preaching to the choir, here. Still, something to watch for.
