The Constitution IS a radically simple document. Compare it to just about any other nation's written Constitution.

What the author says is correct, except that we've spent a couple of centuries accumulating precedents that must all be weighed in making decisions.

While the Constitution is very simple, the accumulated precedents are anything but.

That's what I meant by "not open to interpretation". E=mc² is also a simple expression, but it is a part and parcel of a significantly more complex whole. And to speak more rigorously, my "radically simpler" would pertain to the whole body of constitution + constitutional law even possible around it.

"The Constitution IS a radically simple document." A simple document. Maybe you forgot the Bill of Rights, etc, etc. Simple my a@@. It's interpretation is very complicated and I doubt a plumber, or a teacher, could interpret it. Even college professors are constitutionally stupid.
