Nah, it's not the same thing. She's spoken in public before. She's been on TV railing against Trump people in senate hearings. It's not stage fright, it's her showing that she feels inadequate, while trying to create a facade of being a savior. It shows how scared they are of Pence and Trump when it comes to having to deal with them face to face. They know they're playing games, and they're desperately trying to avoid an embarrassing "ah ha! I've got you now!" moment. Except that's exactly what happened in both debates. Trump did it to Biden multiple times, especially when he brought up Hunter, Biden was standing there with his head down in shame. Those are exactly the moments they want to avoid, but can't.
