The ongoing US war with Iran is reshaping the political landscape ahead of the 2028 presidential election, as former President Donald Trump informally considers potential successors between Vice President JD Vance and Secretary of State Marco Rubio.
According to reports, Trump has privately asked allies whether “JD or Marco” would be better positioned for the future, highlighting growing competition between the two Republican figures as the conflict with Iran intensifies.
The war has exposed differences in their approaches. Vance has taken a more cautious position, reflecting concerns among parts of Trump’s support base about deeper military involvement. Rubio, on the other hand, has strongly defended the administration’s actions and supports a more aggressive foreign policy stance.
Political analysts say the outcome of the Iran war could play a decisive role in shaping the Republican Party’s leadership. A quick and successful campaign may strengthen Rubio’s position, while a prolonged or unpopular conflict could increase support for Vance.
Recent polling from the Conservative Political Action Conference indicates that Vance currently holds an advantage among conservative voters, though Rubio has been gaining ground as the situation develops.
Both figures remain closely aligned with Trump, whose influence continues to dominate Republican politics despite growing public concerns over rising costs and the impact of the war.
Observers note that the Iran conflict is emerging as a defining issue for the Republican Party and could significantly influence the direction of the 2028 presidential race.
