The US Constitution has been rewritten constantly, almost since its ratification. Eg: Chief Justice John Marshall decided in 1803 that the Constitution allowed SCOTUS to strike down legislation if "unconstitutional." That's a rewrite. https://twitter.com/MarshaBlackburn/status/1306633477056598025

The Redemption Era courts rewrote the 14th Amendment to guarantee only the right to contract. Later courts rewrote the Commerce Clause to expand the power of the Federal Government, or wrote in a right to privacy, or marriage equality.

But it's not just courts. Multiple Congresses essentially erased Congress's sole power to declare war, by ceding the power to the Executive. The current Senate, incl. Ms Blackburn, wrote out the power of the purse when they let Trump fund his wall over Congressional opposition.

And, as I like to go on about, the current Senate also radically rewrote the balance of powers between branches when they acquitted the President for treating Congressional oversight as optional.

This process of continuous de facto revision can be used, and has been used, for good and bad ends. But it is a constant, and as much an essential part of our Constitutional history as any clause or phrase in the document.

[Oh, one more: the entire Bill of Rights, not to mention the 13th, 14th, and 15th Amendments, were rewritten to exclude Black people for about a century.]
