It may appear attractive from a MAGA point of view, but it could be overkill, and it is open to a perception of, and even accusations of Nepotism. Furthermore, the Trumps all have day-jobs to keep their corporation up and running, so two Trumps in the US government might not suit.

Nevertheless, the veep appointment is literally not voted for by the people, but decided upon by the President, and allowing such a personal preference structure into a republic is part of the design. Also, to the second point, maybe two Trumps is exactly what will prevent the absurd, combative and toxic situation of the first time round.

Interesting, thank you.
