For years I have percieved her "you know"'s as COMMANDS, subliminal or otherwise. This is the way it is, she pronounces or declares--YOU KNOW THIS IS THE WAY IT IS! And no, I'm not being glib. Wish I were.
No, no -- "you know" is Hillary's "tell". Whenever she's about to drop a whopper, make an outrageous bluff, lay out an unsubstantiatable assertion, she always precedes it with a "you know" or "everybody knows". I like to think that what's left of a conscience in there knows that she's about to lie and throws up that tiny smokescreen in an attempt to hypnotize the listener.
