President Trump's informal polling of about 25 Republican donors and allies at Mar-a-Lago in early March revealed overwhelming preference for Secretary of State Marco Rubio over Vice President JD Vance as the 2028 GOP presidential successor, with attendees cheering Rubio's name. Trump has publicly sidestepped endorsing Vance, despite his vice presidential role, fueling trader consensus on an 87.5% implied probability of no pre-2027 endorsement. This reflects Trump's strategic delay amid party competition and constitutional term limits barring his own 2028 run, with Vance handling high-profile diplomacy like Iran peace talks but lacking heir-apparent status. Odds could shift with primary positioning or late scandal, though historical patterns favor delayed endorsements by incumbents.
