It doesn't matter how clumsy the attempted coup was, there are transcripts, phone recordings, as well as multiple witness testimonies under oath that demonstrate that Trump and his cronies knew that they were pushing a lie, knew that their attempt to bring in false electors was illegal, and knew that they would be inciting violence in our Capitol days and even weeks before the event took place. Hundreds court people have been found guilty in criminal courts--some completely decided by judges and others by juries--for their actions that day. If Donald Trump had not been President with the rabid following that he has garnered, he would already be serving jail time for his role.
Now the Supreme Court needs to decide if it will actual rule based on the text of the 14th Amendment and disqualify Trump from holding any public office again or instead demonstrate their fascist-like loyalty to the man who put three of them on the bench. It's not a question of whether Trump's actions disqualify him or not based on the language of the Amendment; the text is clear. The question is whether the Republican judges are so desperate to keep ahold of Republican power at any cost that they will exonerate a man who has done nothing but tear America down since he was first sworn in to office. We should see by the end of the month.
By the way, attacking a building at a country's capitol in a failed coup and using the court cases as a means to create a cult following is a play straight out of Hitler's book, literally. Hitler wrote Mein Kampf while in prison for his attempted coup in Munich. He used the press to spew his propaganda and gain enough of a following through his lies and manipulation that he had complete control of Germany (and then much of Europe) by the time he was done.
