Excellent article from what I had a chance to read. I will read in its entirety after work.Yes, authoritarian type personalities do tend to lean right, and will lean hard right when they perceive a threat. This is almost entirely related to personality types in the scientific sense of their definition. To spell it out, guardian types on the extreme level, generally translate into authoritarians when placed under perceived threats. These are generally extreme xSxJ types, according to MBTI, (not all xSxJ types).
Yes, Trump is a symptom of a much bigger problem that has been iteratively growing in the GOP since Nixon, (or more correctly, Goldwater). Read Nixon, (strong anti-communist); Reagan, (stronger anti-communist still and brought the religious right into his politics); Newt Gingrich, (converted an entire legislative arm into religious right authoritarians); George W. Bush, (tried to go to war with anything and everything he perceived as a threat); the Tea Party, (all government is out to get you); and finally Trump, (everything about established systems threatens our existence).
I do disagree with the thesis thus far though that this is going to be a perpetual problem. I only disagree on the basis that this problem has evolved as a product of a positive feedback loop that has already destabilized the GOP. The GOP is done, (at least in anything resembling its current form). The positive feedback loop already destabilized it, and now it is time to hit the reset button. This won't continue very long. Social evolution will kill this meme off.
