Two key figures, Vice President JD Vance and Secretary of State Marco Rubio, appear to be the front-runners. Trump himself suggested that Vance is the "likely" candidate to succeed him, while also leaving open the possibility of a Vance-Rubio joint ticket.

Some Trump supporters have floated a third term for the incumbent president, despite that being unconstitutional and there being no clear legal avenues for him to seek a third term in office. An attempt at extending his tenure in the White House would trigger a constitutional crisis and would be unprecedented in modern American politics.

President Donald Trump suggested Tuesday that Vice President JD Vance is “most likely” the heir apparent to the Make America Great Again movement, the furthest he’s gone in backing Vance as a future presidential candidate.
