I don't think it's possible to get that level of mass psychosis again, though not for a lack of trying. MSM has spent all their credibility being propaganda, as did "respectable" Left-wing Youtubers i.e. Breadtuber-adjacent. When people actively stop listening, they become immune to hypnotic suggestion. At least, from the Left. At this point, Trump has to fuck up big with something on the domestic front like with Operation Warp Speed* to galvanize non-TDSers to agree with TDS. I find it unlikely, but that's intuition speaking.
*I am aware the COVID response is not entirely his fault, but it was a case of him reacting to things rather than proacting to events. Likewise, he assumed that Branch Covidian states weren't going to fuck up their own lives to spite him and then they did.
