I don't think that Trump will run again, but who knows? Sleepy Joe is barely standing, I don't see him running again but he is a puppet so there is a chance. We will see.
I think the US will see a Trump Desantis run in 2024. He's likely going to announce soon to get ahead of any legal stuff they're trying to do and also to be the front runner. Announcing early will also make others running on the Rep ticket unlikely.
