I think most Americans have a basic understanding that the Constitution can be amended, but that this is hard to do and therefore is not done very often. We treat our Constitution almost as a sacred text and that is one reason that even though our country is young compared to many others, its form of government has persisted in its current form longer than almost any other (I want to say longer than any other, but someone more knowledgeable than me could probably prove me wrong.)
Anyway, there is another way amendments can happen without the consent of Congress, which is for legislatures in two thirds of the states to force a constitutional convention. Sure, we all read about that when we studied the Colonial period in elementary school, right? I can actually walk over to Independence Hall on my lunch break any time I want and see where that all happened.
It turns out that as of now, December 2017, 28 U.S. state legislatures have voted to call a constitutional convention. 34 states would represent the two-thirds required. This could be a good thing. For example, a constitutional convention could clarify the definition of a “person” and get us the clean elections we so deserve. But that is not what is behind this. What is behind this is people who want to gut the federal government’s ability to tax, provide benefits, regulate interstate commerce, and protect the environment. This could actually be the beginning of the end of the republic.
