The ongoing conflict in Iran is not only shaping US foreign policy but also intensifying the 2028 presidential race, as President Donald Trump weighs potential successors between Vice President JD Vance and Secretary of State Marco Rubio.

According to reports, Trump has privately posed the question “JD or Marco?” to advisers, signaling early deliberations about leadership beyond his term. With constitutional term limits preventing another run, the spotlight has shifted to key figures within his administration.

The two contenders represent contrasting approaches to the Iran conflict. Vance has adopted a more cautious stance, reflecting skepticism toward prolonged US military involvement abroad. In contrast, Rubio has aligned closely with Trump’s hawkish policy, emerging as a vocal advocate of the administration’s aggressive strategy.

Both leaders are actively involved in efforts to pressure Iran into accepting US demands, including dismantling its nuclear and missile capabilities and ensuring free passage through the Strait of Hormuz.

Political analysts suggest that the outcome of the conflict could significantly influence their 2028 prospects. A swift and decisive resolution may strengthen Rubio’s image as a crisis manager, while a prolonged war could bolster Vance’s appeal among voters wary of foreign entanglements.

Meanwhile, Trump’s own approval ratings have taken a hit amid rising fuel prices and growing public dissatisfaction with the war. A recent poll indicated his approval has dropped to 36 percent, adding further pressure on the administration.

Within Republican circles, speculation is growing over Trump’s preferences, with some observers noting subtle signals of support toward Rubio. However, the White House has dismissed such claims, calling them media speculation and reiterating that the administration remains focused on its policy objectives.

The rivalry between Vance and Rubio—once political outsiders and even critics of Trump—now reflects the evolving dynamics of the Republican Party as it prepares for a post-Trump era.

As the Iran conflict continues, it is increasingly shaping not just global geopolitics but also the future leadership of US politics, with both men positioning themselves as potential heirs to Trump’s political legacy.
