Remember the scene in the TV show “Breaking Bad” where Skyler White saves her boss’s butt from prison for income tax evasion by pretending to be a ‘dumb bunny’ bookkeeper?
That’s Clinton.
“the blackberry was back to life when I plug in the charger”, she said! So she doesn’t need much effort pretending to be dumb.
She can even argue “I have emails to prove I am dumb”.
