No insurrectionists in any elected office. Makes perfect sense one would wish to have this key point in one's constitution, heck, even from the beginning. What about insurrectionists who were appointed by insurrectionist(s)? Seems pretty dubious. We need to either remove the insurrectionist appointees, or expand the SCOTUS to water down the insurrectionists in government. Putin must be chortling in his cocoa puffs.
TBH in hindsight, this was only ever a milquetoast alternative to the gallows.
Imagine the alternative timeline in which confederate leaders didn't get to go back to their states and become governors, senators, KKK members, in which the confederacy didn't get to install one of their own by putting a bullet in Lincoln's brain, who would then subsequently veto legislation from congress that sought to prevent southern states from re-establishing with the same leadership that led up to the confederacy.
For that matter, Andrew Johnson as Lincoln's VP had every appearance of signaling a unity ticket (see? we will give concessions if you participate in good faith!) but in retrospect he was effectively the confederacy's deepest mole and most powerful enabler.
Imagine, if you will, the timeline in which confederate leaders were hanged and the confederacy was in fact dismantled vs. being protected from consequence
