I remember the summer of 2016, when I was playing Pokemon Go in the parks and people I had never talked to and that lived nearby were playing it next to me. We were all celebrating when we caught a pokemon when we were after, and comparing which ones we'd caught with each other.
At the time I thought...who would buy Trump's conman routine? Who actually thinks that the country is in a terrible enough place that we need to elect this person who seems to actively hate the country and seemed to want to set the entire thing on fire?
I left my Californian home and went back to my original state to visit my family. We went to several different areas of the state in fall of 2016 because my wife was from a rural area and I originally grew up in a slightly more suburban area. I saw the signs in the yards, I saw the discontent, and I saw how people did not seem to be reacting the same way to his craziness. I saw how casually they would put on his rants in the background while talking about other issues. I saw how some of them were amused by his antics. It had been a couple of years since I had last been back and it once again struck me how much worse the area appeared to be from the last time I was there. I was in a rural area when the "Access Hollywood" tape dropped. People seemed to visibly shrink at even the mention of the news. I thought he was done for, and that this was a bridge too far for his supporters to cross. That people would vote third party, or not vote at all. I did not get the sense that my thoughts were shared by those around me.
When I came back to California, people were talking about the debates. It was sunny and nice out, and people would talk about the projects they had going on in their houses, or they'd talk about work related affairs. People were sometimes amused by Trump's antics, but everyone uniformly thought it was impossible for him to win the election. Having seen what I had seen in the weeks prior, I was no longer one of these people. "They'll never let him win", one of my co-workers said. I was stunned....who are "they"? Does the rest of the country actually believe this?
It turns out quite a few of them did. Many people thought there was just simply no way that Trump would win, because either the system was already rigged against him and would not allow him to win, or because the country was just not in dire enough straits to elect such a madman (as I once thought).
Hindsight is 20/20 but when I thought it was bizarre that he was even a viable candidate at one point in 2016, and I saw the decaying state where I grew up, I thought "if he wins the election, then we are in a much worse state as a country than I thought". And we undoubtedly are.
Of course he won, but the reason that I have this somewhat rambling response to this question is that the answer to "why is he still in the race?" ultimately comes down to the overall state of this country.
He is in this race because this is where we are as a country: barely able to imagine a possible future that is brighter than the present, because we are still caught up in degenerative non-sense that keeps us thinking that our broken down towns, and our poor social bonds are caused by some horde of "others" instead of their true causes: our ever-widening wealth inequality, our ever-decaying moral responsibilities to each other, and our national instinct to absolve ourselves of our responsibilities by claiming that not only is it correct to be forever self-serving, but that even the idea of altruism is a lie.
It's almost like there's greedy fatcats in every industry stuffing all of the profits down their fat gullets while everyone else barely holds off starvation.
