Here’s my take…
I don’t think Trump really wanted to run for President again, but is doing so to:
1) Attempt to shield himself from indictment, which also explains why he announced so early (way too early).
2) Attempt to keep Truth Social afloat (it is on life support now). There’s a lot of private investor money tied up in that project, and if he announced he wasn’t running, that would likely be the end of TS.
Additionally, there are a lot of people whose existence is dependent on Trump being relevant. I’m sure they’ve been in his ear for the past two years. They don’t have his best interests at heart.
I watched his entire announcement speech the other night, and did not see the fire that he had 6 years ago. It’s also clear that his 2016 tactics (nicknames, bullying, etc.) aren’t going to work this time. People aren’t afraid of him anymore.
