I doubt anyone who voted for Trump in 2020 suddenly feels any different about him at this point. Those are Team Red lifers that will never vote Blue, and if he runs again he can count on all of those votes coming back for him at least. The question is where would he make any gains?
He's also someone who actually gets shit done which is a rarity for the modern-day GOP (and politicians in general tbh). Until the past 6 months or so when he has (unfortunately) begun embracing culture war BS like the rest of his party, there was very little he shared in common with Trump other than his visible loyalty.
