By The U.S.-Israeli military campaign against Iran, launched with joint strikes on February 28, 2026, has rapidly reshaped the internal dynamics of President Donald Trump’s administration. As the conflict intensifies, Secretary of State Marco Rubio has emerged as one of the most visible figures managing the crisis—raising early speculation about the contours of the Republican presidential race in 2028.
The war, aimed at dismantling Iran’s nuclear and missile infrastructure while pursuing regime change following the death of Supreme Leader Ayatollah Ali Khamenei, has dominated Washington’s foreign policy agenda since late February. Rubio, serving as secretary of state and a central voice in the administration’s national security team, has appeared frequently in briefings, public statements, and White House events tied to the operation.
His growing prominence has not gone unnoticed inside Trump’s political orbit, according to NBC News.
On the evening the strikes began, Trump hosted roughly two dozen Republican donors at Mar-a-Lago, including New England Patriots owner Robert Kraft. During the gathering, the president informally asked attendees whom they would prefer him to support in the 2028 presidential race: Vice President JD Vance or Rubio.
Accounts from people present suggest Rubio received a notably strong response. One attendee described the reaction as “almost unanimous” through cheers and applause. Another said the split appeared closer, while a third confirmed that Rubio drew significant support from the room that night.
The moment illustrates Trump’s longstanding habit of informally testing political sentiment among allies and donors. According to individuals familiar with the conversations, the president has posed similar questions to advisers, administration officials, and political supporters in recent months as he contemplates the future direction of the Republican Party after his presidency.
While no formal endorsement decisions appear imminent, some observers say Trump’s private commentary has increasingly highlighted Rubio’s performance—particularly as the administration confronts a series of international challenges involving Iran, Venezuela, and possible developments in Cuba.
Public polling among Republican voters, however, still places Vance in a strong position as a potential heir to the MAGA political movement. Surveys in recent months have shown the vice president with higher favorability ratings than Rubio among GOP primary voters. Trump himself has previously described Vance as “most likely” to carry the movement forward and has suggested the two men could potentially “team up” politically in the future.

The unfolding Iran conflict has nevertheless elevated Rubio’s profile in ways few anticipated earlier this year.
When the first strikes were launched, Rubio was present at Mar-a-Lago alongside the president, participating in what aides described as a makeshift war room coordinating the early stages of the operation. Vance, meanwhile, remained in Washington under longstanding security protocols designed to ensure the president and vice president are not both present at the same off-site location during sensitive national security operations.
Although Vance quickly appeared on television to defend the military action and has joined Trump at ceremonies honoring fallen service members, Rubio has taken on a larger share of the administration’s diplomatic messaging surrounding the conflict.
Trump has publicly praised Rubio’s role in managing the crisis.
During the State of the Union, the president declared that Rubio “is going to go down as the best secretary of state in the country’s history.”

The president has also pointed to stylistic differences between Rubio and Vance, describing one as “slightly more diplomatic” — a characterization widely interpreted as referring to Rubio’s role managing foreign policy.
Vance, an Iraq War veteran who built his political identity in part on skepticism toward prolonged American military engagements abroad, has aligned himself with the administration once the decision to strike Iran was made. He has emphasized that the operation should be swift and limited in scope, arguing that Trump would not commit U.S. forces to an open-ended conflict without clearly defined objectives.
The war itself remains politically complicated.
While many self-identified MAGA voters support the strikes against Iran, broader public opinion polling shows more skepticism about Trump’s handling of the conflict. Foreign military interventions have long been controversial within a Republican Party increasingly shaped by “America First” priorities.
Some analysts inside Trump’s broader political network warn that Rubio’s association with the policy could become a liability if the war drags on or loses public support.
Administration officials, however, reject suggestions of internal rivalry.
A White House spokesperson said the administration remains unified and focused on national security objectives, dismissing media speculation about a potential 2028 showdown between Rubio and Vance.
Privately and publicly, both men have also sought to tamp down talk of competition. They remain on friendly terms, speak frequently, and have appeared together at several administration events in recent weeks.
Rubio has expressed support for Vance as a possible future nominee, and said he won’t run for president if Vance decide to run himself.while Vance has often deferred to Rubio’s leadership on foreign policy matters.
Trump has made clear he expects to play a decisive role in shaping the party’s future leadership. He has repeatedly suggested he would likely endorse a successor in the Republican primaries.
