I feel like you also have people who've read it enough to understand that a rewriting of the Constitution would lead to them losing power. The deification of the Founding Fathers makes the Constitution a sacred document and you don't change sacred documents.
Which is funny because the Founding Fathers understood that the Constitution shouldn't be a sacred document. While this is the only base law the USA has had in two centuries, this was the third base law for the overall country they lived in within their lifetimes.
It wasn't most people, but there were a lot.
