Your naivete is being taken advantage of by bad faith actors.
* This is not true because <some sound logic or data source>
Instead, you just wrote that I'm naive and pretty much left it at that.
Why does this topic make you do that?
(Edit: just noticed that your profile even says you're a data scientist of all things!)
If you are not an American, I suppose it makes sense that you are not aware of the current political climate. If you are American, then you've been deliberately ignoring the obvious.
There's enough. Aggregating various recent polling, it seems that about 1 person in 8 is OK with that, and maybe 2 more (for a total of 3/8) are passively in favor - that is to say, they won't do anything about it, but won't object if it happens. You don't need a majority of people to support a coup; indeed, that's kinda why it's such an attractive option to the unscrupulous.
An important problem nowadays is that our media and interpersonal communications take place at lightning speed, but out political technology is many respects still rooted int he 18th century, and our administrative technology covers a span from 19th century unresponsive bureaucracy to 21st century oppressive surveillance. Politics as presently constituted does not work well for a lot of people, and so they are not invested in maintaining the status quo.
Put simply, our economic infrastructure is highly distributed, but power is highly centralized and that makes a lot of people angry.
