That may be the next fight.They can be recalled, that's true. (You are living in a fantasy world if you think anyone's going to jail for what happens at a convention). Which is probably why they'd invoke a secrecy provision, just like the Founders did, to prevent something like that from happening why they work.
If a Convention happens (with a secrecy provision), then I would instruct the delegate to remain in place and vote no on everything that comes up until the secrecy provision is lifted.
And do you believe that a secrecy provision would hold up in this day and age? The Founders were gentlemen. When they promised not to divulge the dealings of the Convention, they generally kept their word.
We live in a world with Democrats. They did not.
If secrecy is enjoined, I would direct the Virginia delegate to vote against secrecy, and then take out his iphone, set it on the table and record all day every day and then "accidentally" release the entire recording every night, or, failing that, to take copious written notes and "accidentally" release the notes every night.
What court would prosecute a delegate to a Convention of States for violating an injunction of secrecy that he had voted against?
