I wonder if she wore bright red to draw attention away from her podium at the end, when she walked to the other side of the stage and waved at people.
I think she was pretty sure all camera eyes would be on her, but if you look closely at the video, she looks down an awful lot and not at the camera. And after she’s delivered her teleprompter message, she giggles and wriggles like a pleased little five year old. Those ‘involuntary’ hand movements we were shown previously, are NOT involuntary, she’s SCROLLING! Anyone with a Mouse will recognize that movement.
That video is worth watching a number of times. I found it fascinating.
