Victor Davis Hanson, previously cited in these pages, has some comments about how revolutionary parties die out, or don't, with caveats. I'd take the Napoleon-Stalin model more seriously if I were him: both of them came out of "nowhere" (Corsica and Georgia, respectively), and took over a group of disaffected people. Read the article. Comment as you see fit.
Update I'd take the Napoleon-Stalin model even more seriously once you notice that while Trump is restrained by the Constitution, his opponents are not. The courts around the United States are no longer interested in interpreting the law: they want to approve whatever high-handed measures the Left is taking in their state. Oppression is cool for Leftists, while they accuse the Right of plotting it, and say how awful the Right is to do so, they actually do it and approve of it. As noted here, the Left deliberately inverts the idea of "responsibility" and "punishment" to encourage those out of control to destroy things. It recalls this “Necessity is the plea for every infringement of human freedom. It is the argument of tyrants; it is the creed of slaves.” – William Pitt's remark should be the reminder that we are individuals, and do things differently because of it, not seeking the uniformity of necessity.
Retraction Don Surber points out that some courts restrain the government over-reach and uses Michigan as his example. I am duly abashed, and exempt Michigan from my critique. For the moment.
