My primary concern with Trump as the potential nominee is that he has likely made himself unelectable in 2024 with his actions since 2020.

People tend to make up their mind about the various candidates running and then vote against the candidate that they dislike more. In 2008, people voted against McCain because he represented four more neocon years in the image of Bush, and everyone was tired of it. In 2016, people found Hillary so personally loathsome that they came out to vote against her. In 2020, four years of TDS (that both the media and Trump himself helped create) made people vote against Trump.

I think die-hard Trump supporters vastly underestimate how many moderates, swing voters, and normies have TDS and will never vote for him. Even given the choice between the corrupt fuckup Biden and Trump, they'll still vote Biden because these people have made up their mind and will not change it. That's why I think that Trump is unelectable.
