Trump needs to point out to the audience that when Hillary is nervous... “She smiles more..” This will put her in a double bind where she is afraid to smile and appears more nervous... and... it’s true!!!
Fantastic!! Get this idea to the Trump campaign!
Actually, I think when she LIES she smiles more. She is trying to make us believe her lies while smiling at us. And since she knows she’s lying, that is probably what’s making her nervous.
