It's all irrelevant in way, in the sense, like Lenin or Hitler or Mao or Kim.
Trump at this point, even more than 2016, is more or less just a figurehead surfing Punch puppet upon definite and significant groundswells of fear,anxiety and discontent legitimately out there among legions of supporters (followers).
I sense it growing shfting too now
This zeitgeist mindset and shift seems palpably different and has moved on somehow from Reagan or each of the Bushes type reflection of a classical (Republican) political loyaty.
Their WILL be a more sophisticated version of everything Trump preens and puffs himself on. There's not going to be some figurehed Gorbachev, Justin, Nelson, Jacinda, AOC movement by way of relief or legitimate change from all this at some point near or distant term.
This horrific reality now meets mechanisms, pundits and powerbrokers that actively or surreptitiously stoke, feed or fund it.
Look at Europe, same thing's happening.
Fourth Estate and forward looking Rationalists and those that know History are now at the point of more or less of just sitting on the side-lined beach building sandcastles on shifting sands while these populists and their henchpeople at the same trough are swimming and dog-paddling behind as Trump I(Putin - Erdogan, Netanyahu etc ) comfortably ride powerful waves and swells of ignorance and very human edgy panicked notions and emotions wanting, nay needing and craving 'leadership' that's 'strong' and so perceived regardless of its actuality (or even promised outcomes).
It's too hard or fearful for most to genuinely comprehend outcomes in years ahead of much which many demographics and in different walks of life daily face or look ahead to. It's like populations are kiddies wanting the bedtime stories and Santa to sort out some new dawn of joy and present fucking relief.
It is same as reasonng someone who believes in God say, that person CANNOT be dissuaded from their path or that belief just as the opposing athiest cannot: it's too key to their ontological identity, selfhood.
It takes apostasy or major breakdown to shift either mindset in any meaningful way, if at all, or it only abates and slightly evolves for (ontologic) survival.
Reality is worldwide its become a cultural turf war swirling around (economic) livelihoods for individuals rich and poor together alongside organisations, countries and corporate behemoths with those very same concerns.
2020 or 2024 if we're talking just USA won't really shift that anyway is my take.
It's like post WW1/ WWW2/ Glasnost and now say, loss of NATO or EC and traditional alliances are all now shifting and morphing up for grabs once again. Who knows where we'll end up at this point?
Trumpians and anyone following on from 2020/2024 will STILL be surfing that.
TL: DR we're kinda fucked, and the only thing knitting us together are at least the structural checks and balances of nation states in place (and only some countries).
