That's fair, they definitely waited too late. I guess I also wonder, what if they just left Biden as is. They believed he was going to win, heck he got 80M+ popular votes when he ran. Why risk swap him out. But then, I think, once they did swap him, she could have boosted her position by emphasizing how she will do things better. But perhaps she was also honest and didn't want to lie and she didn't really plan on changing anything.
