President Donald Trump has begun informally polling friends and advisers to determine who would be the more effective Republican presidential nominee in the next election, weighing the prospects of Vice President J.D. Vance against Secretary of State Marco Rubio.
This internal deliberation reflects a broader preoccupation with his own legacy, which has become a recent obsession for the president. While the administration had long viewed J.D. Vance as the presumptive front-runner for the 2028 nomination, current dynamics suggest a shift in momentum toward Rubio.
Marco Rubio, who serves as both the secretary of state and the national security adviser, has significantly increased his public visibility. He has recently appeared in high-profile settings ranging from the Vatican and the White House briefing room to ringside at UFC fights. Observers note that Rubio, who appeared glum during the early stages of the administration, now appears to be enjoying his role. This shift is mirrored in focus groups conducted by pollster Sarah Longwell in April 2026, which indicated a renewed interest in Rubio among MAGA voters.
However, Rubio’s ascent occurs while he serves as the primary spokesperson for a conflict in Iran that is described as an unpopular war and a strategic catastrophe. The U.S. Government has struggled to define clear goals for the conflict or establish a viable path toward achieving them, a situation that could potentially jeopardize Rubio’s future electoral prospects.
In contrast, J.D. Vance has maintained a lower public profile in recent months. Vance expressed skepticism regarding the Iran war in its early stages and has continued to raise questions about the conduct of the conflict. While Vance has denied reports that these questions are intended to maintain favor with the president or target the press, he continues to hold a lead in Republican favorability.
According to Pew polling conducted earlier in 2026, three out of four Republicans view Vance positively, compared to two out of three who view Rubio positively.
The divide between the two potential successors is not merely a matter of polling, but of personality, and ideology. Rubio is perceived by some voters as more human than other figures in the administration and is seen as less ideological than Vance. Conversely, Vance is often characterized as smirking and censorious, and Rubio’s previous attempt to run for president yielded results described as underwhelming and robotic.
The Succession Paradox
Any successor to President Trump faces two primary systemic challenges: maintaining the MAGA coalition and appealing to the general electorate.
The MAGA coalition, assembled through Trump’s personality-based politics and ideological flexibility, is beginning to splinter. This fragmentation is driven in part by criticism of the president’s handling of the war in Iran. Both Rubio and Vance are considered latecomers to Trumpism compared to many of the movement’s core voters.
The second challenge involves the need for a candidate to distance themselves from the aspects of Trump’s presidency that have made him historically unpopular with the general population. A successor must achieve this without alienating the president or his most dedicated supporters, a balancing act complicated by the president’s influence and vengeful nature.
The conflict in Iran serves as a microcosm of these challenges. The war has had significant economic repercussions; as of May 11, 2026, the national average gas price reached $4.52 a gallon, an increase of approximately 50 percent since the start of the conflict. In response to surging fuel prices, President Trump has expressed a desire to suspend the federal gas tax, though such a move requires congressional approval.
The current state of the conflict remains precarious. On May 11, 2026, President Trump stated that the ceasefire in Iran was on
“life support”
after talks between the U.S. And Iran stalled. According to Iranian state media, Tehran has demanded an end to U.S. Sanctions, recognition of its sovereignty over the Strait of Hormuz, and war reparations in exchange for negotiating an end to the war and reopening shipping lanes.
The paradox of the president’s focus on his legacy is that the very actions he has taken to establish it—specifically the attack on Iran—may make the electoral landscape significantly more difficult for whichever successor, whom he reportedly refers to as “kids,” he eventually chooses to anoint.
