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.
