Ok, as I understand it:

Convention of the States IS the common vernacular Constitutional Convention. The Founders specifically enshrined Anything not federal powers is up to the States.

This is WHY local state representatives are important elections.

The state legislature calls for the convention, and may name articles they(the state) are concerned with. Then the governor passes it or not like any other legislation. the legislature or governor elects two people to represent/argue-send to the COS (your state rules may vary)

When 2/3 majority of States call for a convention, then it's called, and has the power of assembly. Huge debate, states submit the articles they want, and the entire body boils it down to articles they can agree upon -Again 2/3 of those state representatives must vote up or down on the articles to become actual articles they present for ratification.

There's a high hurdle, 2/3 is a large majority hurdle, hell, even the location & times will be a brawl. Wako stuff may be presented for consideration, but again 2/3 of the state reps need to agree on the articles & wording, Essentially only one or two or three articles at most will actually be voted to present back to the states -So the scare of bullshit changes to the constitution is largely that a scare or subterfuge, hard to get two people to absolutely agree, much less than 100...

THEN

The articles agreed upon get sent back to the states to ratify. they argue in local legislatures, probably meet with people, maybe even local referendums, eventually the state legislature votes to ratify yea or nay, and present it to the governor, who signs it or rejects it. -Just like any other state legislation.

If the State ratifies it, that is a "vote" that is sent to U.S. CONgress, who's only role at that point is tally-keeper.

If 2/3 of the states "vote" to ratify one, or all the articles, then the amendments are automagically passed, if less than 2/3 they are defeated. There may or not be a symbolic vote in the house, made by the state reps -I am not clear on that formality. but the reps are bound by their state's position. Essentially, like the impeachment vote, congress acts like the tally-keeper and Roberts, they can only say it passed or not by count. NOT inject any other bull----

So, it won't be any radical changes, unless 2/3 of the state legislatures are radical leftists.

At most, it could be articles such as: Balanced budget mandate, Term Limits, maybe NO-Sharia Ever, maybe a reversal of roe v wade, or change to immigration.

There will be many other articles submitted and debated and voted upon, but it really is going to be limited as to what passes by 2/3 of the states AGREEING on an articles.

The Convention of States, is the remedy of States to reign in a rogue CONgress or to get issues raised that CONgress has dropped the ball long enough to piss the states off.

It's the LAST thing CONgress wants to occur, as it renders them impotent. There's also a good incentive for Congress itself to ACT, Because Articles of Constitutional Amendments, can also occur in & BY CONGRESS, as has happened with most of our other amendments...So a COS can be a good incentive for spurring a Do-Nothing Congress, into action.

So really, a COS can submit ANYthing, but the high bar of 2/3 of the states agreeing, curbs the utter nonsense pundits put forth. they could even LIMIT CONgress' Powers, give the president more, End the fed etc. Provided that the majority of the states agree the action is necessary.. it could go on for months, even years, and could be mooted by Congress actually acting before the states ratify their articles.

Bottom Line it's a message to Govt, that the PEOPLE & their state Legislators will have remedy one way or the other....

make sense ?
