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.

Instead, it’s Secretary of State Marco Rubio, who again was talked up as a potential running mate by current Vice President JD Vance in 2028. Vance, who holds a formidable lead in all polling of the still-conceptual Republican presidential field in 2028, did not say no when Fox News’ Maria Bartiromo asked if he was looking at 2028.

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.
