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.
That says a lot when a college freshman seems more capable then a 46 year old
