Since the actual ability within the populace to write went missing years ago (image the Constitution as a tweet), and since today's culture may not know this, let me be reiterate that the document was 'drafted', meaning the author wrote and thought at the same time. It used to be a common practice to write a statement, and then to consider it in context with the expectation that changes were likely to occur. This doesn't mean he f'd up or someone was holding a gun to his head forcing him to change his mind.
Thinking about what you write and why and how it should be cached for your audience used to be a worthwhile goal.
