Article V of the U.S. Constitution describes the process by which the Constitution can be amended. In short, all amendments are legal except:
In short, no amendment could be passed before Jan 1 1808 affecting the slave trade and no amendment can be passed that will affect any state’s equal representation in the Senate. In short, you can’t pass an amendment that says “North Dakota has no senators.”
However, what if we really had it in for North Dakota. The other 49 states have really decided that North Dakota doesn’t deserve it’s senators… heck, they make up 2/3 of the state population anyway. And besides, they’re not going to secede… the Army would just wipe the floor with them.
But we can’t just pass a “no ND senators” amendment… it’s illegal under Article V.
However, what’s to stop us from amending Article V to get rid of the last clause and then passing our anti-ND amendment?
