The constitution doesn't need to be interpreted. It's written in plain English under the common law.
We run into all the problems with "interpretations" when we let the black robed class that is trained in admiralty/corporate/statutory law that was instituted in 1871 after the United States ceased to be a constitutional republic and became a corporation tell us what the constitution means.

Between legalism growing and morality shrinking, we now have a country that the legal profession dominates, and common sense - the constitution - gets trampled on more & more as the people lose any sense of decency, self respect, honesty and responsibility; not to mention the strong suction hold that the teats of gov. has on so many!!
All that is needed to confirm this is that the ZERO got a second term.
