Trump is the symptom and not the disease. The disease is the people who Trump has managed to latch on to. Sure, he likes the strong man aspect but he is just the carnival barker craving attention as he has always been. The reason that the problem didn't go away when Trump was defeated is that the disease is still here. Trump will be the Republican nominee, he won't be elected, he may not even be allowed to be on the ballot in some states depending on court case outcomes. The main lesson from the Trump years is the potential fragility of democratic institutions, the way that the Republicans caved in to Trump and the electorate backing him. The good news is that the system is finally working to punish the Jan. 6 crowd but that element is still out there. All that actually has little to do with Trump. He just ran at the right time to get their vote. Years ago he supported Hillary Clinton as I recall when she ran for the Senate. He doesn't really represent anything other than himself. He may end up in prison (or house arrest) in due time but until the "disease" is cured there will be others to carry on that brand of populism.
