Enacted in the wake of the Civil War, Section 3 of the 14th Amendment disqualifies from public office any individual who has taken an oath to uphold the U.S. Constitution but then engages in insurrection or rebellion against the United States, or gives aid or comfort to its enemies. No prior criminal conviction is required.
Trump was targeted by plaintiffs in cases for his role in “inciting and facilitating” the insurrection at the U.S. Capitol on Jan. 6, 2021, just after the November 2020 general election in which President Joe Biden defeated Trump.
Claiming the Democrats “cheat” is lazy. There has been no credible evidence of any of the kind of mischief the Trump camp was up to.
That said, I am in complete agreement with you that the Democratic party’s commitment to free and fair elections is a complete sham. Every aspect of the primary process is designed to give the establishment of both parties every opportunity to manipulate voters.
As for third party ballot access, that is one of the least important issues with the election system. With first past the post, third parties will always be irrelevant or spoilers. That has to be fixed first.
But here is the real difference. Fixing our election system means fixing the laws that govern it. But that does absolutely no good if the laws are ignored. Trump has to be held accountable for his open lawbreaking, or election reform is nothing but public masturbation.
