As for 2024 - it is obvious now that the only way the GOP can win another election is by dismantling democracy.
There is no chance whatsoever that the GOP can win again without wilfully disenfranchising tens of millions of voters. In spite of the bot mob on Twitter trying to create the impression there's some kind of enraged far right majority agitating for representation, the reality is the numbers just aren't there for a clean win.
So that is what is happening now. 2020 is the last chance for the far right, and they know that - which is why they intend to take the shot well before 2024.
I don't think that's true. There are plenty of moderates in the the swing sates that voted for Biden but would be more than willing to jump on the bandwagon for someone who is seen as a moderate conservative and making the right promises. The trick is getting that candidate through the primaries if the scene looks like 2016, where the hard hard right will gather around the one nut job, and the other 5 establishment republicans will be indistinguishable.
After Trumpists, tea partiers and evangelicals it will be interesting to see what happens next. The latter two groups seemed happy to align with trump despite not sharing their core values, maybe the trumpists will stick with whatever the next group is.
I believe the context here is that Sovereign Citizens and some Q people believe that this is the date that Trump assumes a new term.
March 4 was (haven’t verified this myself) the original inauguration date. So says a podcast I listened to about conspiracy theories.
