To add to my admittedly curt answer:
If Trump runs for President in 2024, he is all but certain to be the Republican nominee. No Republican with any future in the party will dare oppose him, and he would steamroll over a Larry Hogan or other “never Trump” candidate. So that alone puts him in an excellent position.
The other factor here is that Republicans are in a strong position to win back one or both chambers of Congress in 2022. Should they do so, any remaining Biden legislative initiatives are DOA. Republicans will use their chairmanships and investigatory powers to turn every perceived misstep or impropriety by the Administration into a media circus (e.g. Benghazi). If they take the Senate, they will similarly turn every executive or judicial branch nomination into a high-profile showdown. And they will hope (not without reason) that Biden will take the blame for “getting nothing done” and not “being bipartisan.”
