Could be, though I’d question the prolificness. I guess that’s why the mods come down on us so hard. You can’t be certain of anything because…well, there ARE Russian bot-farms, Trumpers (even teams of them operating in tandem), and of course True Believers ™, and short of catching the guy in the act and examining his rig, you can’t be sure what you’re dealing with. That said, IMO, there’s not really a huge difference between them when it comes to debunking them. A vote for a third party is a vote for the major party most opposed to your third party in the USA. At least until we get RCV in more places!
A couple of points I’d add to this:
Trump is a symptom, not the cause. Put another way, should Trump choke on an overcooked steak tomorrow and die, the threat won’t be ended. The cancer is the entire GQP, not just its leader.
Americans as a whole have a desire for authoritarianism. ‘Make those bad people behave the way I want them to’ is endemic in American culture.
Not only can it happen here, it has, twice, and damn near took our Democracy down with it both times.
