This is correct. I don't think it is possible to design a democratic system that is impervious to authoritarianism when a large enough percentage of the population is in favor of it. After the last election, it is clear that a slight majority of Americans are either in favor of outright authoritarianism or are at least not turned off by it.

I wonder how much is this is "rational" due to Congress being broken as an institution. Hyper-partisanship and an unchecked filibuster means that Congress is stuck in permanent gridlock. The only way to get anything done is through executive power. But the system wasn't designed to work that way and so the checks on executive power can seem stifling to progress. It seems that many are willing to look the other way if they feel like its the only way to get what they want done. Concern only seems to come into play when its the other side wielding power. And this seems to be true across the aisle. Many on the left were frustrated with Biden's perceived timidity when it came to exercising executive power. And I feel like he was pressured into doing things that he wasn't fully comfortable doing unilaterally (especially regarding student loan forgiveness). Of course, the difference is that Biden spent 40 years in the Senate, understands the role of Congress in government, and had no intention of "ignoring the rules". Trump isn't limited by that type of thinking since he had no experience with, no great knowledge of, or respect for American government.
