I think Biden will not be renominated in 2024, and even his presence as the incumbent President will be a detriment to whomever the Dems nominate. I think the calculation will be that his resignation (for health reasons) and the elevation of Kamala to the Presidency will be less damaging, since a huge black voter turnout is essential their chances of winning.Maoist/DSA Democrats are closing ranks around him. They'd rather re-elect Biden, no matter how incompetent and corrupt he may be, then lose the White House.
