You’d think a hegemony with a 100-years tradition of upkeeping democracy against major non-democratic players, would have some mechanism that would prevent itself from throwing down it’s key ideology.
Is it really that the president is all that decides about the future of democracy itself? Is 53 out of 100 senate seats really enough to make country fall into authoritarian regime? Is the army really not constitutionally obliged to step in and save the day?
I’d never think that, of all places, American democracy would be the most volatile.
I mean, I think they’d have considered a civil war less than 100 years after the founding of the country to be a pretty good indication of failure.
As for the modern world, they explicitly talk about trying to design a system so that a tyrant doesn’t become president. All the supposed checks and balances that were supposed to prevent that turned out to be as effective as wet tissue paper. The founders also cared a lot about the president not being corrupt, and drafted the emoluments clause(s) to prevent that, and Trump has just completely ignored those clauses. I think they’d have been pretty upset about that, and wondering why the law of the land was just being ignored.
