No, my dream scenario is very much that Russian involvement in undermining American democracy had been taking place for years before Donald Trump was ever a thing, and it was being done via right wing media. I want an entire generation of world views collapsing. Fox News, Rush Limbaugh, et al., were nuts and ripping this country apart long before Donald Trump decided to run for President. Trump is the symptom, right wing media is the disease. It's right wing media that's driving what you describe in your post, the total movement away from facts and into crazy land.
But, again, this is just a dream scenario, I don't expect it. Occam's Razor is that these people were just doing it because it made them a lot of money.
I'm just exasperated and don't know how we deal with these people. You can't win a debate based on facts, because these people reject even the concept that there are facts. And until you get the right debating within the realm of actual facts, there's no "fixing" the GOP.
