In addition, the demographics of today's America is not the demographics of the 1780's. We were one people then, today we are a cesspool. The delegates to any convention today could not even understand each other, linguistically and culturally.
Actually, the majority of the delegates to the Convention of States would understand each other perfectly, because they would be there for exactly the same reasons: to propose amendments to the United States Constitution that impose fiscal restraints on the federal government, that limit the power and jurisdiction of the federal government, and that limit the terms of office for its officials and for members of Congress.
That's it... what's so hard to understand about that?
