In the perfect world, he won't run and the left will have a better candidate to offer. Hopefully one that has good enough electability to beat a trump or a desantis as well as offering improvements over Biden.
If there's no one else who can win on the left, then Biden it is then
@deadgerbil As A Republican I’ll say this. He’s no Bernie Sanders. Bernie was 82 during the 2020 cycle and had charisma and energy and got people excited. I do not see Biden being that in 2024
