I don't think that the integrity of elections and democracy are the main point of this essay.
Orwell wrote a lot about authoritarianism, and as you say, "communism" was the prime example at the time.
What he hints at here is not only the fragility of democracy. It's about the fragility of civilization.
It's about the "will to power" as defined by Nietzsche, and the power of belief systems, as well as the primal underpinnings of our society.
This essay makes me think about the authoritarian side of capitalism, "freedom" (to take what you can), slavery and many more topics.
My takeaway is that our contemporary masquerade of "capitalism=freedom=human rights" is nothing but an illusion of a select few.
But that's what makes Orwell great, everybody reads him differently.
I'm well aware that Orwell is favored for "anti-socialist"/"pro-freedom" stances and I have read 1984 and Animal farm.
