The Constitution cannot be understood because it’s so old?
The canard that the Constitution cannot be understood is a favorite of those who wish to find things that aren’t there and deny things that are. The 1803 Marbury vs. Madison case, in which the Supreme Court set itself up as the arbiter of the Constitution, and the following cases where the Court ignored the letter of the Constitution in order to find new provisions and dismiss existing ones has led directly to this.
The six pages of the constitution are simple enough that a high school student that couldn’t figure it out should not graduate. Is the language a bit archaic? Yes, I’ll grant that, if you’ll grant that the failure of the public schools to teach English. It’s certainly easier to understand than the deliberately obtuse 2500 page bills passed in the dead of night designed to restrict the liberties protected by the Constitution, in order to elevate “pubic servants” to the new aristocracy.
