This article has been making the Internet rounds for the past couple of weeks, and is starting to get some attention as it becomes clear that Trump will be the Republican nominee.

From Vox:

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. He later repeated the same poll in South Carolina, shortly before the primary there, and found the same results, which he published in Vox:

As it turns out, MacWilliams wasn’t the only one to have this realization. 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.

More through this link. I’m not sure I agree with all of the premises upon which the argument is based, but it is a serious piece worthy of some discussions.
