Technically the Constiytution isn't a (social) contract, but is it a legal instrument. We couldn't survive if the courts monkeyed around with most legal instruments the way they do with the Constitition. But blame John Marshall, who was the first to put spin on the words of the Constituition.

Elliot's Debates contain a wealth of information on exactly what the Founders meant. Without having to resort to later judicial activism and reinterpretation.
I never said it was a 'social' contract.
If one reads the assorted treatise and legal writings quoted by the Founders (along with the writing of the Founders themselves) it is plain that the Constitutional contract, formed by the civil entities of the States, created a statutory entity of the United States with express local federal powers and limited national powers.

True, but they can 'monkey' with it all they like. Since anything repugnant to the Constitution is automatically null and void, their 'monkeying' doesn't change the letter or the law of the Constitution, it only tries to confuse it.
