As in 1787, today’s states would send delegates, not representatives. There is a big difference. As opposed to our congressmen and senators, amendment convention delegates will be agents of the states. Delegates from states that actually wished to restore republican freedom would arrive not with plenary powers, but would be subject to legislative instructions that restrict their jurisdiction. Limited to specific areas, and perhaps backed up with enforceable sanctions, it would take a bold delegate to dishonor his commission.

He is assuming that the state legislatures will select delegates and give them narrow instructions, but Article V doesn't say so. Even if the states call for a convention, it is likely that the delegates will be popularly elected.

It wouldn't make sense for a state legislature to promote a popular delegate election subsequent to deciding an amendment convention was needed to correct specific problems.
