Hazony replied by email that the statement is intended

to permit a public life rooted in Christianity and its moral vision in those parts of the United States in which a majority of voters support such a public culture. This is in keeping with our endorsement of the federalist principle in Clause 3. There are many states in the United States where no such majority exists, and the Statement of Principles does not envision using the national government to impose such a public life on those states. The point is to return “church and state” issues to the states to be resolved through the democratic process.

In her March 2022 paper, “Illiberalism: a conceptual introduction,” Marlene Laruelle, a professor of international affairs and the director of the Institute for European, Russian, and Eurasian Studies at George Washington University, provides a four-part definition of the term:

Illiberalism is a new ideological universe that, even if doctrinally fluid and context-based, is to some degree coherent; it represents a backlash against today’s liberalism in all its varied scripts — political, economic, cultural, geopolitical, civilizational — often in the name of democratic principles; it proposes solutions that are majoritarian, nation-centric or sovereigntist, favoring traditional hierarchies and cultural homogeneity; and it calls for a shift from politics to culture and is post-post-modern in its claims of rootedness in an age of globalization.

Laruelle argues that there are significant differences between illiberalism and conservatism as it has been traditionally understood:

The key element that dissociates illiberalism from conservatism is its relationship to political liberalism. Classical conservatives — such as the Christian Democrats in Europe or the Republican Party in the U.S. before Donald Trump — are/were fervent supporters of political rights and constitutionalism, while illiberalism challenges them. For classical conservatives, the political order is a reflection of the natural and family order, and therefore commands some submission to it. For illiberals, today’s political order is the enemy of the natural order and should be fought against.

In a 2021 Wall Street Journal op-ed, “Why America Needs National Conservatism,” Christopher DeMuth, president from 1986 through 2008 of the mainstream Republican American Enterprise Institute and now chairman of the National Conservative Conference, reinforces Laruelle’s point: “When the American left was liberal and reformist, conservatives played our customary role as moderators of change. We too breathed the air of liberalism, and there are always things that could stand a little reforming.” But, DeMuth continued, “today’s woke progressivism isn’t reformist. It seeks not to build on the past but to promote instability, to turn the world upside-down.”

The doctrines of progressivism have resulted, DeMuth argues, in

mayhem and misery at an open national border. Riot and murder in lawless city neighborhoods. Political indoctrination of schoolchildren. Government by executive ukase. Shortages throughout the world’s richest economy. Suppression of religion and private association. Regulation of everyday language — complete with contrived redefinitions of familiar words and ritual recantations for offenders.

How deep is the reservoir of support that national conservatism can tap into? The striking pattern in polling data shows that over the years from 2017 to the present, Trump, despite all his liabilities, has retained a consistent favorability rating, ranging from 41 to 46 percent of the electorate, a base that appears virtually immovable.

Arlie Hochschild, a professor of sociology at Berkeley and the author of “Strangers in Their Own Land: Anger and Mourning on the American Right,” has been interviewing voters in Eastern Kentucky’s Appalachia since 2018, exploring the reasons behind this unwavering loyalty.

I asked her about the prospects of illiberalism in this country and she replied by email: “We should keep a close eye on the sense of grievance stored up almost as a springboard within the word ‘stolen.’ ” The background to this, Hochschild argued,

is that blue-collar, rural/small town — especially white and male — have since the l970s been the “losers” of globalization, and the two parties now represent two economies. To this demographic, economic loss is compounded with a loss of fallback sources of honor — gender, sexuality, race — for white heterosexual males these, too, seem under attack. This is the “deep story” of “Stop the Steal,” and they see reality through that story.

The story does not end there. Hochschild continued:

The right believes that it is the left, not the right, that is moving toward fascism. Inside the right wing mind today freedom is threatened “by the left.” Political correctness a form of “thought control.” The left controls the media. The F.B.I. is scanning Facebook to hunt down patriots in Washington. So, ironically, they see themselves as brave upholders of freedom, democracy, civil liberties. They aren’t saying we want strong totalitarian control so we get to impose our values on others. They see themselves as the victims of this control and Trump as their liberator from that control.

Still, national conservatism faces significant hurdles. For example, Hochschild pointed out, this country recently saw a dramatic change in the Kansas electorate: “In the days after the Supreme Court’s Dobbs decision leaked, Kansans turned out in record numbers in the primary and delivered a victory for abortion rights, a win fueled by Democrats out registering Republicans by 9 points since the Dobbs decision was announced, with a staggering 70 percent of all new registrants being women.”

How dangerous, then, is America’s current right populist movement?

Tait, the historian of conservatism, is cautious in addressing this question, noting that national conservatism seems to “represent something new in that it seems to explicitly depart from liberalism instead of reproducing it in a compromised, conservative way.” He described the Edmund Burke Foundation’s Statement of Principles as

an effort at a mature, sanitized post-Trumpism. But a great many of the guardrails of constitutional liberalism and fusionist conservatism have been undermined and we may see a politics less constrained by liberal constitutional norms and rules. Likewise, the actors prominent in this space are less constrained by right-wing respectability politics, including Ron DeSantis and Josh Hawley.

Damon Linker, a senior fellow at the Niskanen Center, sees a strong parallel between trends in the United States and the illiberal developments in Europe. Referring to the recent election in Italy, Linker posted “What just happened in Italy?” on his Sept. 26 substack, Eyes on the Right, arguing that

We’re left with a picture of a country in which the center-left is supported mainly by the educated, secular, and professional classes, while the right appeals to a cross-section of the rest of the country — the working class as well as the middle and upper-middle classes, along with the religiously pious and the large numbers of Italians who treat religion as a symbol or identity-marker without actually believing in or practicing it.

If that sounds familiar, Linker continued,

that’s because similar things have been happening in many places over the past decade. The precise political results of these shifts have varied from country to country as they’ve interacted with different electoral systems, but the underlying trends in public opinion can be seen to a greater or lesser extent in France, Great Britain, the United States, and other countries. In each case, the center-left has gone into decline with the center-right and anti-liberal populist right rising to take its place. Until the center-left figures out a way to win back the working- and middle-class, as well as the nominally religious, it will continue to lose precious political ground to the populist and nationalist right.

William Galston, a senior fellow at Brookings, points out in an essay, “What Is National Conservatism? The movement could be the future of the American right,” that “Two of illiberalism’s most important intellectuals, political theorists Yoram Hazony and Patrick Deneen, have mounted a frontal attack on the entire individualist, rights-based liberal political tradition that they trace back to John Locke.” In Eastern Europe, this critique resonates, Galston continued, but “it does create a problem for the United States where, historians inspired by Louis Hartz have argued, political liberalism is our tradition.”

National conservatives, Galston argued,

do not distinguish between the liberal political tradition and the excesses of today’s liberal culture. They see the focus on individual rights — and on the conceptions of equality and liberty that flow from them — as corroding traditional beliefs and practices. They are convinced that they must sacrifice the liberal baby to get rid of the progressive bathwater, and they are all too eager to do so. Embracing unfettered majoritarianism in the pursuit of virtue is no virtue. It is hard to overstate the danger to pluralism and liberty that lies at the end of this road.
