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.

While polls show the vice president is the favorite for the GOP ticket in 2028, the president has increasingly floated the secretary of state for the top job.

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.
