They just run the annointed candidate in the primary. Harris never got more than 1 or 2 percent.
Unless Harris wants to go, they will never quietly push her out. Personally, I think now that she’s had a ringside seat, I don’t think she’d want the job as President for long. But once they get rid of Joe, she’s the President, like it or not. I’m thinking they’ll pick someone as her VP that they think can win in 2024.
