I feel like we can stop right there. In this most recent election, the purported authoritarian won a straight majority of votes. He's lost support since then, but even so, he has a very large base of support.

The article suggests that the threat has to be "obvious". Tens of millions of Americans dismiss the threat entirely.

I suspect that a lot of his partisans wouldn't support a clear violation of the two-term limit, but consider the precedent of Putin, who installed a proxy. Suppose that Trump decided to run for Congress; is there any doubt that he'd win, and be made Speaker? Or get himself made Chief Justice?
