And?
Would you have the citizens vote on each and every document? Of course not.
The citizens elect the president. The president, decides what documents are presidential documents and what documents are personal documents.
The Administrative state is not elected. They don't decide what is a presidential document.
"The executive power shall be vested in a President of the United States of America". That's what the Constitution says. If you don't like that then amend the Constitution.
Incorrect. It's clearly spelled out in the law what is Presidential, and what is Personal. And the scope of what is Personal is extremely limited. See post 74 for the exact text.
