Why Donald Trump selected Sen. JD Vance (R-Ohio) as his running mate is still unknown. What did Trump see in Vance, who once called the former president “America’s Hitler” and unfit for the presidency? And what caused this transformation?

Assuming Congress and the states do not repeal the 22nd Amendment to allow presidents to serve more than two terms, Vance will likely be the Republican frontrunner for president in 2028.

Trump must believe that with the proper guidance and mentorship, Vance could be a successful president. But aside, from his children, Trump has managed to avoid having any proteges rise to high office.

In fact, the number of former senior officials Trump chose to serve in his first administration (including his vice president) who are now in strong opposition to his reelection should be instructive.

If one fast-forwards to 2027, when presidential candidates will be announcing, Vance will almost certainly be one of them. Clearly, his ambition will be an issue.

From Vance’s perspective, should Trump win, actuarial tables show that there is some probability he will not complete his term of office. In the worst case, that could make Vance president or acting........
