I had the same thoughts about her myself. Not everyone is a great speaker in person. Some people are just better on paper, meaning they are more thoughtful and not as able to come up with the snappy response in person. That is my impression of her. She knows what she’s doing as long as somebody is not demanding something from her in front of the camera. I say that as someone who I think is like her, I am not snappy and crisp in responses if they are being demanded of me on the spot. But if I can be thoughtful and put my thoughts down on paper, I am a much better thinker. Or at least I appear to be. I am not saying I am as smart as she is, but I think that is a common personality thing, which is why I think I understand it.
