I'll hold back from worrying about a Barron based dynasty until he EVER opens his mouth in public to speak. The public doesn't even know what he sounds like. Why is he so quiet? Does he sound like Pee Wee Herman? I have gotten the impression that helicopter Mama Melania doesn't really want Barron to be infected with Daddy Trump's stink though as he's an adult now, it's up to him. He is tall though. That's generally a plus in politics. However, he's freakishly tall which likely cancels that out.
I suppose he does likely share the politics of Daddy, though I think if he flipped the script and went anti-Trump, he could really be something special.
