Trump sought and actively tried to subvert constitutional government and overturn the results of the presidential election. And what he could not do through the arcane rules and procedures of the Electoral College, he tried to do through the threat of brute force, carried out by an actual mob.
The front runner and probable nominee. I think its clear he violated the 14th amendment, and because this is/has/will be a political issue he needs to run, and he needs to loose.
If he is denied the chance to be on the ballot as valid as it may be then he can justify everything as proof the system is rigged, so he should get to rig it in his flavor, with violence and war if needed.
So…why have the 14th amendment?
A good question and I don’t know if I have a valid argument either way.
