And that's true, but I think it's important to note that Trump is a symptom, not the disease itself. The disease is his base, and the corruption of their belief in democracy. I hope I'm wrong, but I feel like we'll see this level of politics for a while more.
It goes both ways, really. You're right in that Trump couldn't have gotten elected without the existence of that reactionary base. That's always existed in American politics, though its strength has varied over time. However, his presence in politics energizes them, and inspires them to organize and spread their propaganda, while also serving as a powerful propaganda mouthpiece himself.
You're also right that Trump's exit from politics won't calm things down right away. Hopefully his movement won't find a new Fuhrer figure, though that's always a possibility.
