I think honestly he would be Trump's preferred "successor" if Barron wasn't another 17 years from being able to run for Prez. His other kids seem mostly politically inept, especially Don Jr. This is mostly "vibes" but none of them really match to Trump's undeniable charisma. Trump is a very skilled bullsh*tter, while Don Jr., Eric, etc... aren't.
Despite literally just being 18 something strikes me as different about him.
Barron is a clean slate. I don't think I've ever even heard him talk. He has baggage, never gone on the record on policy, isn't on social media (at least publicly). He really can morph himself into whatever he wants. He could turn out to be a carbon copy of his father or he could be a decent, dignified, pragmatic statesman. He already has the last name so that gives him carte blanche for pretty much anything he wants in GOP circles. I can see a viable political future for him
