[ That would be awesome, until it gets overturned by SCOTUS. COS is a nice idea, but wed better be prepared to use physical force to keep it in tact. Which will essentially be nullification, which we could just do without spending time and money on COS. ]
COS is a viable exit ramp from the road to the cliff we are on right now. SCOTUS cannot over turn a Term Limit if it is ratified, they can only “Interpret it” which in the case of Term Limits is pretty Cut and Dried, if they try to mess with something like it may bring the phrase: “hung Jury” to mean something different.
Any COS must use clean simple plain language in any thing it proposes before sending it off to 3/4 for retification. Otherwise you are right that the SCOTUS may interpret it weirdly. The simpler and more plain the better. Amendments should not be written for the Lawyering class, but in plain language for the ones who consent to be goverened.
That is not to say it shouldn't be done, but the question is "Who will enforce it?"
