I believe I predicted about two years ago that Biden would never run in 2024, so you could expect him to step down in early 2023. That way, the cackling c-word would get to be "president" and run as an incumbent, but without triggering a full official term because it would be less than two years.
More importantly, since everyone hates Kamala Harris, it would allow them to install a "vice president" who they think is their real most likely shot at winning the 2024 election, so that they can have the benefit of a nice important-sounding title as well.
It's all the same anyway, Biden, Harris, and whoever else they might appoint are all just party stooges.
