There’s zero reason not to vote for someone else that you agree with more in the Democratic primary (assuming they didn’t cancel the primary in your state like they have in many).
What are the two outcomes? Either Biden wins the nomination, and maybe eeks out a win against Trump, or you get a better nominee who is more fit to win the general due to both Trump and Biden having basement level approval. It’s not exactly a win-win, but it doesn’t hurt anything either, especially when the incumbent is as unpopular as someone with 90 something felony counts. Literally anyone running in the dem primary would be better than Biden in a general.
