Michele Bachmann really wants you to know she’s a “constitutional conservative.” The term is featured prominently on her web ads. She mentioned it three times in her announcement speech. It’s in the first sentence of her official bio. But what exactly does it mean? While the term can signify different things to different people, it turns out it’s especially important to Bachmann. As a candidate who doesn’t want to get confined to a social conservative ghetto in an election year that is revolving around fiscal and economic issues—and as someone with a well-earned reputation for extremism—her strong “constitutional conservative” stance indicates, but only to those who are trained to listen, a decidedly radical agenda that is at least as congenial to rabid social conservatives as it is to property-rights absolutists or anti-tax zealots. In short, it enables her to run as a middle-of-the-road conservative who just wants to get rid of ObamaCare and balance the budget, even as she lets the initiated know she has other, more ambitious, plans for the country.

Despite the growing ubiquity of the “constitutional conservative” identifier in the Tea Party movement and the right-wing blogosphere, there’s no authorized definition of the term and some who proudly wear the label doubtless disagree about its meaning. Adam J. White of the Weekly Standard attributes its recent emergence to an influential 2009 essay in the Wall Street Journal by the Hoover Institution’s Peter Berkowitz. The Berkowitz formulation did indeed focus on the need for Republicans to return to first principles, with “the constitutional order” providing the key optic. But he also called “moderation” in the pursuit of liberty an essential constitutional concept, which is not a term one would normally associate with Michele Bachmann or Constitution-brandishing Tea Party activists.

Among this crowd, it more commonly connotes an allegiance to a set of fixed—eternally fixed, for the more religiously inclined—ideas of how government should operate in every field. Constitutional conservatives want to distinguish themselves from the more tradition-bound type of conservatives who adapt to changing social and economic needs and, for that matter, to the perceived wants and needs of the populace. They rarely come right out and denounce democracy, of course, but it’s clear they think their liberties are endangered by people who, say, would like government-guaranteed access to affordable health care.

Conservative polemicist and radio host Mark Levin offered an exceptionally clear explanation of the connection between this kind of affinity for the Constitution as the sum of political wisdom and a degree of hostility to democracy:

[F]or the Founding Fathers, individual liberty was not possible without private property rights. For the Founding Fathers, the only legitimate government was not only one that was instituted with the consent of the people, but one that would preserve and protect the individual’s right to property. Jefferson talked about it, talked about ‘tyranny of the legislature.’ So the consent of the governed is only part of it.

Levin’s words are an appropriate reminder that constitutional conservatives think of America as a sort of ruined paradise, bestowed a perfect form of government by its wise Founders but gradually imperiled by the looting impulses of voters and politicians. In their backwards-looking vision, constitutional conservatives like to talk about the inalienable rights conferred by the Founders—not specifically in the Constitution, as a matter of fact, but in the Declaration of Independence, which is frequently and intentionally conflated with the Constitution as the part of the Founders’ design. It’s from the Declaration, for instance, that today’s conservatives derive their belief that “natural rights” (often interpreted to include quasi-absolute property rights or the prerogatives of the traditional family), as well as the “rights of the unborn,” were fundamental to the American political experiment and made immutable by their divine origin.
