The last guys that had to deal with these kinds of traitors, left us with a great tool to deal with this exact situation, called the 14th Amendment/ Section 3:
No person shall be a Senator or Representative in Congress, or elector of President and Vice-President, or hold any office, civil or military, under the United States, or under any State, who, having previously taken an oath, as a member of Congress, or as an officer of the United States, or as a member of any State legislature, or as an executive or judicial officer of any State, to support the Constitution of the United States, shall have engaged in insurrection or rebellion against the same, or given aid or comfort to the enemies thereof. But Congress may by a vote of two-thirds of each House, remove such disability.
This perfectly describes Trump, and every person who gave speeches at the pre-Insurrection rally, as well as anyone who amplified the Big Lie that the 2020 election was stolen, which was the premise for the Insurrection.
All it would have taken was a Biden Administration courageous enough to use the exact words in the Constitution to protect us from the resurrection of MAGA. If Lincoln could have seen that, he would have been screaming: "Why the fuck do you think we went to the trouble of amending the fucking Constitution? To keep traitors like these assholes from taking over again, you dopey dipshits!"
