With Donald Trump's victories in South Carolina and Nevada, America's Authoritarian Spring is now in full bloom.

Trump's rise has raised questions about a current political science theory that describes how the presidential nomination process works and continues to bedevil pundits who argue Trump's vote share is capped and his voters come from the same anti-establishment "lane" as Senator Ted Cruz's.

Let's take a look at all three of these issues.

First, in their book The Party Decides, leading scholars of American politics argue that political party insiders, defined quite broadly, exert considerable influence over the presidential nomination process, starting with "invisible primaries" and continuing to actual primary nominating contests where votes are cast and delegates are selected.

In the Republican nominating process this year, at least so far, party insiders are not in control. American authoritarian voters are, and their candidate of choice is Donald Trump.

Take South Carolina. My survey of South Carolinian Republican voters found that authoritarianism was one of only two variables that was a statistically significant and substantive predictor of support for Trump. A voter's gender, education, age, evangelicalism, ideology, party identification, income and race simply had no statistical bearing on support for Trump.

The survey was conducted over the last five days leading up to the GOP primary. It predicted Trump would win 33.3 percent of the vote in South Carolina and forecast a second-place showing by Senator Marco Rubio. Its findings mirror the results of the national survey conducted under the auspices of the University of Massachusetts Amherst reported here last month.

The importance of authoritarians to Trump's success is readily apparent in the chart below, which arrays predicted probabilities of supporting him, Senator Cruz and Senator Rubio across the authoritarian scale.

This chart also captures a fallacy at the core of the pundits' contention that Trump and Cruz are running in the same anti-establishment "lane" and, as such, competing for the same voters. Trump and Cruz may be in the same lane, but there is a big yellow line that divides it right down the middle.

As with Trump, authoritarianism was a statistically and substantively significant predictor of Cruz's support in South Carolina. But the sign of the authoritarian coefficient was negative, meaning it is non-authoritarians who were much more likely to support Cruz. In South Carolina, the so-called anti-establishment Republican vote was divided into two parts, and the authoritarian part of the vote was larger.

Finally, the second statistically important predictor of Trump's support in South Carolina was a variable that links authoritarianism and those who are more likely to worry that they or someone in their family will be a victim of terrorism.

This connection, or negative interaction, between perceived threat and authoritarian behavior was first identified by Marc Hetherington and Jonathan Weiler. Its influence on political behavior, when threat is defined as personal fear of terrorism, was demonstrated by Hetherington and Elizabeth Suhay in 2011 in their article in the American Journal of Political Science.

The practical implication of a negative interaction between increasing perceptions of threat and authoritarianism is that those who are not strong authoritarians behave in a more authoritarian manner when confronted by threat.

This is exactly the behavior found among South Carolinian supporters of Trump. Voters who were more likely to fear terrorism were also more likely to vote for Trump even though they were not predisposed to be the strongest authoritarians.

These results should be a big red flag to those who argue Trump's support is capped. It is not. Fear of threats from "the other" is also a significant driver of Trump's support. As Trump expands his litany of threats facing America to include economic threats from the Chinese, Vietnamese, Mexicans and other "others" he "likes," the appeal of his authoritarian message reaches a broader audience spanning partisan lines.

Union voters and other classic Democratic defectors become prime targets for Trumpism, as threats from terrorism and immigration and to the economy and jobs are combined into one systemic threat to America, a threat that, in Trump's estimation, can only be met by strongman Trump.

The implications of authoritarianism, threat and the interaction of threat and authoritarianism in the general election, if Trump wins the Republican nomination, should not be underestimated.

Those Democrats who think Trump will be an easy opponent to defeat in November may be whistling past the graveyard, resembling the Republican establishment and commentators who dismissed and ignored his candidacy for too long.
