The American media, over the past year, has been trying to work out something of a mystery: Why is the Republican electorate supporting a far-right, orange-toned populist with no real political experience, who espouses extreme and often bizarre views? How has Donald Trump, seemingly out of nowhere, suddenly become so popular?
What's made Trump's rise even more puzzling is that his support seems to cross demographic lines — education, income, age, even religiosity — that usually demarcate candidates. And whereas most Republican candidates might draw strong support from just one segment of the party base, such as Southern evangelicals or coastal moderates, Trump currently does surprisingly well from the Gulf Coast of Florida to the towns of upstate New York, and he won a resounding victory in the Nevada caucuses.
Perhaps strangest of all, it wasn't just Trump but his supporters who seemed to have come out of nowhere, suddenly expressing, in large numbers, ideas far more extreme than anything that has risen to such popularity in recent memory. In South Carolina, a CBS News exit poll found that 75 percent of Republican voters supported banning Muslims from the United States. A PPP poll found that a third of Trump voters support banning gays and lesbians from the country. Twenty percent said Lincoln shouldn't have freed the slaves.

MacWilliams studies authoritarianism — not actual dictators, but rather a psychological profile of individual voters that is characterized by a desire for order and a fear of outsiders. People who score high in authoritarianism, when they feel threatened, look for strong leaders who promise to take whatever action necessary to protect them from outsiders and prevent the changes they fear.
So MacWilliams naturally wondered if authoritarianism might correlate with support for Trump.
He polled a large sample of likely voters, looking for correlations between support for Trump and views that align with authoritarianism. What he found was astonishing: Not only did authoritarianism correlate, but it seemed to predict support for Trump more reliably than virtually any other indicator.

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.
