The smartest woman in the world doesn’t know how classified information is noted. The smartest woman in the world had an incredible lack of curiosity about how classified information is handled. Given her jobs as senator and secretary of state, if she’s really the smartest woman in the world, she should know that such jobs will involve classified or secret information.
The smartest woman in the world is just too dumb or too dense to understand the gravity of secret information, how its handled, how its disseminated, etc.
To paraphrase her, she was so inept at all this, yet she wants to have the nuclear launch codes.
