I wouldn't be surprised if they're just waiting for one of the myriad left-leaning orgs to do something like January 6th to justify an anti-communist purge and takeover. Doesn't even have to be actual socialists. It just has to be enough for the media to spin into a justification. I can see it now: every socialist or socdem org being outlawed, any liberal who doesn't become an ardent anti-communist getting arrested for questioning, etc. Finishing what McCarthy started.

After all, all those handy "anti-insurrection" laws didn't come into effect until after the right tried their embarrassing coup. And all of those laws happen to be applicable to any leftist org "trying to overthrow the government". I could see some extremely agitated Antifa action escalating via interference and the media just making it out to be a fullblown takeover. I know people working for the government who swear up and down that Antifa is a highly organized, evil, foreign communist threat because other friends in the government tell them so. It really wouldn't take much convincing.
