WASHINGTON: As the war in Iran threatens to imperil President Donald Trump’s legacy, the political stakes also are rising for two of his top lieutenants: Vice President JD Vance and Secretary of State Marco Rubio. The pair, widely viewed as potential successors to Trump, have been thrust into still-developing negotiations to end the ?war at a moment when the Republican Party is already weighing its post-Trump future.
Vance has taken a cautious approach, reflecting his skepticism toward prolonged US military involvement, while Rubio has aligned himself closely with Trump’s hawkish stance and emerged as one ?of the administration’s most vocal defenders of the campaign.
Trump has said both men were involved in efforts to force Iran to accept US demands to dismantle its nuclear and ballistic missile programs and allow oil traffic to pass freely through the Strait of Hormuz.
With the next presidential election due in 2028 and term limits barring Trump from running again, the president has been putting the succession question to allies and advisers in private, asking “JD or Marco?,” two people familiar with his views said.
The outcome of the US military operation now in its fifth week could shape the two men’s 2028 prospects, political analysts and Republican officials said. A swift end to the war that favors the ?US might bolster Rubio, who also serves as Trump’s national security adviser and could be seen as a steady hand during a crisis. A prolonged conflict could give Vance space to argue he reflected the anti-war instincts of Trump’s base without openly breaking with the president.
Trump’s own standing is also at stake. His approval rating fell in recent days to 36%, its lowest point since he returned to the White House, hit by a surge in fuel prices and widespread disapproval of the ?Iran war, a four-day Reuters/Ipsos poll completed last week found.
Some Republicans say they are watching closely for which senior aide Trump appears to favor as the Iran conflict unfolds. Some see signs of Trump leaning toward Rubio but note he could change his mind quickly.
