I was saying that the right aligned influence operations pretend to be democrats and help get the moderates the nominations because they can beat them to be clear your quote makes it sound like I said the opposite.
My point though, by the time it gets to the general election, it's already over. There is zero percent chance of stopping the fascists with them running the opposition. Moreover people that stick their necks out for democracy get them chopped off even if the democrats win an election in spite of themselves, as Biden squeaked out a win against a president with 40 percent approval hated more than any man in the country by half the population.
As such, it's not the fault of those that didn't vote democratic, it would change nothing, fascists were going to win the moment they got establishment candidates in there.
Beyond that, whose fault is it people voted third party? Those establishment figures do nothing but spite the left. People made clear they won't vote for democrats if they get continually worse, if they continue to betray issues we care about, and they openly spite us at every turn. We knew they wouldn't get those votes if they continued to be sold out hacks, and they did it anyway, knowing what the republicans were, and what the electorate was.
As such, it's wrong-headed to blame voters. Keeping a doomed to fail strategy despite knowing it can't win negates any criticism they have of voters for not betraying their own interests and supporting candidates owned by the rich that openly spite them worse every cycle. They made clear they won't support them if they do x or don't do y, and they did x and didn't do y. If they got the support anyway, they would continue to get worse, already further right, further sold out to big money, than George HW Bush let alone Nixon. Biden really was giving George W Bush a run for his money.
It is wrongheaded to blame voters, and belies being susceptible to the buck passing arguments the establishment uses to stay in power to fail again. Don't fall for it.
