Yes. And not just that. He is 40 years old. He can potentially have a full political career ahead of him. Trump is doing his very best to destroy the GOP, with Vance they might have a hope in future.
His wife is Indian. A telegu. Comes from a whole family of academics. They were class mates in law school. Certainly she is not a lady to marry a stupid man. I am Indian, and no modern educated Indian young lady will do such a thing. So bottom line the speeches JD is giving now is not the line he will walk in future. He is too smart for that. He is taking a bet on himself for the reason you mentioned. Next in line alongside a 78 year old lunatic who can be manipulated.
