I too thought Sarah delivery was perfect. Her voice not only delivered her sarcastic humor to a ingenious level, she twisted it like a knife in the backs of her targets. I would love to see her smack down one of the DemonRAT untouchables in a debate.
I agree. I noticed that her delivery had more force at just the right moments and she hesitated at just the right times before delivering the punch. She was always great but last night was perfect!
