Miles away, in an office at Vanderbilt University, a professor named Marc Hetherington was having his own aha moment. He realized that he and a fellow political scientist, the University of North Carolina's Jonathan Weiler, had essentially predicted Trump's rise back in 2009, when they discovered something that would turn out to be far more significant than they then realized.
That year, Hetherington and Weiler published a book about the effects of authoritarianism on American politics. Through a series of experiments and careful data analysis, they had come to a surprising conclusion: Much of the polarization dividing American politics was fueled not just by gerrymandering or money in politics or the other oft-cited variables, but by an unnoticed but surprisingly large electoral group — authoritarians.
Their book concluded that the GOP, by positioning itself as the party of traditional values and law and order, had unknowingly attracted what would turn out to be a vast and previously bipartisan population of Americans with authoritarian tendencies.
This trend had been accelerated in recent years by demographic and economic changes such as immigration, which "activated" authoritarian tendencies, leading many Americans to seek out a strongman leader who would preserve a status quo they feel is under threat and impose order on a world they perceive as increasingly alien.
These Americans with authoritarian views, they found, were sorting into the GOP, driving polarization. But they were also creating a divide within the party, at first latent, between traditional Republican voters and this group whose views were simultaneously less orthodox and, often, more extreme.
Over time, Hetherington and Weiler had predicted, that sorting would become more and more pronounced. And so it was all but inevitable that, eventually, authoritarians would gain enough power within the GOP to make themselves heard.
At the time, even Hetherington and Weiler did not realize the explosive implications: that their theory, when followed to its natural conclusion, predicted a looming and dramatic transformation of American politics. But looking back now, the ramifications of their research seem disturbingly clear.
Authoritarians are thought to express much deeper fears than the rest of the electorate, to seek the imposition of order where they perceive dangerous change, and to desire a strong leader who will defeat those fears with force. They would thus seek a candidate who promised these things. And the extreme nature of authoritarians' fears, and of their desire to challenge threats with force, would lead them toward a candidate whose temperament was totally unlike anything we usually see in American politics — and whose policies went far beyond the acceptable norms.
A candidate like Donald Trump.
Even Hetherington was shocked to discover quite how right their theory had been. In the early fall of 2015, as Trump's rise baffled most American journalists and political scientists, he called Weiler. He asked, over and over, "Can you believe this? Can you believe this?"
This winter, I got in touch with Hetherington, MacWilliams, and several other political scientists who study authoritarianism. I wanted to better understand the theory that seemed to have predicted, with such eerie accuracy, Trump's rise. And, like them, I wanted to find out what the rise of authoritarian politics meant for American politics. Was Trump just the start of something bigger?
These political scientists were, at that moment, beginning to grapple with the same question. We agreed there was something important happening here — that was just beginning to be understood.
Shortly after the Iowa Republican caucus, in which Trump came in a close second, Vox partnered with the Washington-based media and polling company Morning Consult to test American authoritarians along a range of political and social views — and to test some hypotheses we had developed after speaking with the leading political scientists of the field.
What we found is a phenomenon that explains, with remarkable clarity, the rise of Donald Trump — but that is also much larger than him, shedding new light on some of the biggest political stories of the past decade. Trump, it turns out, is just the symptom. The rise of American authoritarianism is transforming the Republican Party and the dynamics of national politics, with profound consequences likely to extend well beyond this election.

The field, after a breakthrough in the early 1990s, has come to develop the contours of a grand theory of authoritarianism, culminating quite recently, in 2005, with Stenner's seminal The Authoritarian Dynamic — just in time for that theory to seemingly come true, more rapidly and in greater force than any of them had imagined, in the personage of one Donald Trump and his norm-shattering rise.
According to Stenner's theory, there is a certain subset of people who hold latent authoritarian tendencies. These tendencies can be triggered or "activated" by the perception of physical threats or by destabilizing social change, leading those individuals to desire policies and leaders that we might more colloquially call authoritarian.
It is as if, the NYU professor Jonathan Haidt has written, a button is pushed that says, "In case of moral threat, lock down the borders, kick out those who are different, and punish those who are morally deviant."
