It may not be going out on a limb at this point, but I’m making the call on Biden right now.

1. he spends the weekend at home “resting, recovering, thinking”
2. returns to White House early next week, Monday or Tuesday
3. lays low, but before the week’s end, staffers declare a “major announcement” imminent from the president
4. gives a “Cross Hall” White House announcement something to the effect: “After consulting with my family, and for personal health reasons, we’ve decided it is in everyone’s best interest for me to pass the torch of the Democrat party. I am withdrawing my name as a candidate for the 2024 party nominee.”
5. turn, walk down the hall, turn right
6. turn the page; Democrats begin to reminisce the “incredible” job Biden did for America, practically saving the nation from certain ruin, and go “whole hog” on Harris

We’ll see how it plays out.
