This election was a nihilistic attempt to bring down the elite for its own sake, which is postmodern. It's children playing with fire. It was not about the people or government returning to our founding principles, it was about rejecting elitism, intellectuals, scientific facts, enlightenment ideals, democratic republic virtues, etc. to push their own very limited worldview into the government as a whole and our leaders seem incapable of stopping it. The average Trump supporter is just a member of the populace who is feeling disenfranchised and wants their fair share of the pie based on their heritage and the color of their skin. They are no different than the very people they are criticizing. Our subpar politicians are catering to them instead of defending the higher ideals of our constitution. It has degenerated into "keeping our guns from the government". It's as if that's all they have left. Instead of participating by better educating themselves and demanding better, more educated candidates in office, they just want someone who is going to spew the same uninformed nonsense in Washington.
A direct democracy is the end result of everyone thinking their opinions are just as good as someone's knowledge and demanding that they be heard in government. In modern times, it has been heavily influenced by postmodern thinking, if indirectly. Think of Fox News, CNN, and MSNBC, who both report without the integrity of objectivity. As part of their entertainment package, they point fingers at the other's political bias and use that to justify their own biased reporting. While I doubt all of these journalists read postmodern literature, they certainly report as if they do. A direct democracy certainly can lead to anarchism and totalitarianism, as the masses look for a strong leader to pull them out of the mess they helped create.
Donald Trump has cashed in on this fact. He knows how the media works and used this to his advantage to obtain the power he desired. His timing could not have been better. He knows Americans are desperate for a "strong" anti-establishment leader that can pull them out of the uncertainties they are drowning in. He is their self made man who bucks the system, their anti-hero, their superman.
