Barron is his closest son and likely the heir to Trump. Problem is he can't run until 2044 so I wouldn't be surprised if he wants to see Don Jr. be President between the gap. Trump would likely want to see at least one of his kids become President before he passes away, and I don't think Trump will live long enough or be in good health by the time Barron is eligible.
You don't think Donald Trump will live to be 98?
He might but even if he does it seems unlikely that he would be in a state to enjoy life like he does now. Most people at that age are in assisted care and a lot are suffering unfortunately.
