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.

Rather, 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.
