I don't think Trump even wants to be president again. He knows he wasn't good at it.
I believe he's running primarily in hopes of shutting down the prosecutions against him and avoiding prison or financial ruin as consequences of his own actions.

I doubt it matters to tRump whether he is good at something or not. He cares about the prestige and the profit that he can exploit.
He has a pathological need that overrides any want.
He reportedly plotted a coup because being second felt embarrassing to him.
He is a sad sack. It is hard to imagine, how needy he feels to not acknowledge 70mio votes telling him that they "approved" of him.
