I would say her general demeanor, her presentation style, if you compare her to 2020, she has clearly gotten better at speaking and energizing a crowd. She seems more polished, more self-aware. I don’t know if she was leaning towards Shapiro, but if rumors are to be believed, she listened to feedback from progressives and chose Walz. Plus, y’know, she’s a rational adult who isn’t a malignant narcissist or raging egomaniac.
