The investigation was done by a private content mill, which makes the research a bit questionable given their interests - lots of potential for cherrypicking examples and so on. There aren't that many states mentioned in the article, but those that are were either blue already, or deeply-entrenched red states that wouldn't have made a difference at all in the final result even if there was an upset.
Also - would literally anything come out of this? Dems don't even have the spine to oppose monarchies (not making this shit up, look at the "few notes" section) let alone confront an active, powerful administration in a meaningful way.
Fully aware you're being mockingly sarcastic, but there's some truth to that - democracy and fascism aren't some "polar opposites", but rather just a form of class rule and you get one or the other depending if times are good. If times are relatively alright, you have normal democracy and elections, and when they're not (with there being risks of severe class conflict or overthrow), that's when you get fascism to concentrate capital and suppress dissent.
Also, a "working democratic system" doesn't say much when there's nothing more to it than billions in campaign funds and media to decide who's getting elected.
