How will they ignore term limits? How would they ignore a repeal of the 17th Amendment? How would they ignore a state veto over their actions?
"the operators need to be replaced"
And how, exactly, would you propose we do that? Let's hear your plan! I don't know about you, but I've been trying to do just that for at least the last 40 years.
You’re far more optimistic than me about the what would come out of a constitutional convention populated by the types of “statesmen” and women we are cursed with today. Their perfidy toward the constitution we have now is one point, but I honestly dread what might emerge from a gaggle of today’s politicians, almost all of whom are likely to be lawyers (as opposed to the mix of classically educated propertied men - no women - newly emerged from the Revolution who spawned what we have) and other categories of thieves. And to answer your question about to go about changing the “operators” the ballot box is the only way short of resorting to another kind which I’m not inclined to mention.
