Get a "Guilty" on something. Cuff DJT in the courtroom. Hustle him to jail which will very quickly result in "deep depression" and "suicide." I believe them quite capable and likely to accomplish their vital mission that way as all other ways inevitably backfire. They don't even care that almost all Americans will see through the tactic and 60-70% will be horrified while the children will be singing and dancing. Killing him will backfire, too but they believe they can handle that and he is then no longer alive to lead the opposition. If they kill him the will probably go all in on the Police State with deadly SWATs all over the country on prominent and not so prominent but known Conservatives.
The Republic, or what remains of it, can transmogrify into the Total Marxist State in a day.
What percent of all LEO’s do you think will participate in firing on fellow Americans?
Of those few that would, what is that number in comparison to the freedom loving gun owners in America?
I don’t think your “in a day” scenario can happen to an armed society.
We live in interesting times!
