Secretary of State Marco Rubio has cut Vice President JD Vance's lead in New Hampshire's 2028 GOP presidential primary poll from 46 points to just 10, a shift that signals the next Republican nomination fight may not be a coronation.
The University of New Hampshire Granite State Poll, released this week, puts Vance at 36 percent support among likely Republican primary voters in the state that has hosted the first GOP presidential primary for a century. Rubio sits at 26 percent. No one else cracks double digits: Sen. Rand Paul of Kentucky and former South Carolina Gov. Nikki Haley each drew 8 percent, Florida Gov. Ron DeSantis grabbed 6 percent, and everyone else tested at 4 percent or less.
Those numbers alone would be unremarkable. What makes them matter is the trajectory. In the previous UNH survey, conducted in February, Vance commanded 53 percent to Rubio's 7 percent. Fox News Digital reported that Rubio has gained 19 points since then, while Vance has shed 17, a 36-point swing in roughly five months.
The shift did not come from a campaign launch or a big-dollar advertising blitz. Rubio does not have the kind of political team that Vance has already assembled, a group of advisers who would form the skeleton of a presidential campaign if Vance runs. Instead, Rubio's rise appears tied to the job he already holds.
As secretary of state, Rubio has crisscrossed the globe, and his portfolio has grown heavier. His role in the U.S. operation in Venezuela and the ongoing conflict with Iran has kept him in front of cameras and in the headlines. President Trump has amplified that visibility, declaring earlier this year that Rubio would go down as "the greatest secretary of state in history."
Vance, meanwhile, has been building out his own political operation, including tapping a new chief of staff with deep Trump-world ties. He has not formally declared for 2028, and he has pushed back on the idea that any rivalry with Rubio exists at all.
On Fox News' "The Story," Vance addressed the speculation head-on:
"I think it's so interesting the media wants to create this conflict where there just isn't any conflict."
In a separate interview with Fox News' Martha MacCallum earlier this year, Vance called Rubio "my closest friend in the administration."
Whether or not the two men see a conflict, others in the party clearly do. Fox News confirmed earlier this year that a group of GOP donors supporting Rubio has been quietly exploring ways to boost the secretary of state's political profile. That effort drew a sharp response from an unnamed operative in Trump's political orbit, who told reporters that "the divisive stories from some donors trying to cause chaos are not helpful."
The same operative insisted that "Vice President Vance is the future of the Republican Party, and Marco Rubio is one of his closest friends in the administration." That framing, loyalty, unity, no daylight, is the official line from Vance's corner.
Rubio, for his part, has said he will back Vance if the vice president launches a 2028 campaign. But saying you'll support a friend and declining to build your own political infrastructure are two different things. Rubio's rising poll numbers, his growing public profile, and the donor activity around him all point in a direction that "support" language does not fully capture.
David Carney, a New Hampshire-based Republican consultant and veteran of numerous presidential campaigns, offered a blunt read of the landscape:
"There's nobody else in the conversation besides those two, so this poll makes sense."
The UNH poll's internals reveal a split that could shape the 2028 primary if it hardens. Newsmax reported that Vance's support is strongest among self-identified conservatives, where he leads Rubio 49 percent to 29 percent. Rubio, however, performs better among moderates and libertarians, the voters who often decide New Hampshire primaries.
That dynamic echoes a familiar pattern. New Hampshire's open-primary structure has historically rewarded candidates who can pull from beyond the party's ideological base. If Rubio continues to consolidate moderate and libertarian-leaning Republicans while Vance holds the conservative lane, the math tightens fast.
Two-thirds of likely Republican primary voters in the survey said they want the party's 2028 nominee to build on Trump's presidency. Just 28 percent preferred a different direction. Both Vance and Rubio can credibly claim the "build on Trump" mantle, Vance as his vice president, Rubio as his top diplomat, which is precisely what makes the contest so volatile.
Vance has been the subject of intense public attention beyond the 2028 question. He reflected candidly on past missteps in a recent memoir on faith, and his personal life has drawn scrutiny from the left and curiosity from the right in equal measure.
President Trump has done more than anyone to keep both men in the conversation, and more than anyone to leave the question unresolved. He said last year that Vance is "most likely" his heir apparent, adding, "In all fairness, he's the vice president." But he has also called a hypothetical Vance-Rubio ticket "unstoppable," without specifying who should sit at the top.
That deliberate ambiguity gives both men room to maneuver and keeps both dependent on Trump's favor. It also creates risk. An unnamed longtime Republican strategist, speaking anonymously, framed the danger for Vance in stark terms:
"Vance is in the catbird seat until something really goes bad, and Trump is going to blame him.... I can't imagine Vance walking this tightrope for two more years without p***ing off Trump."
That warning captures the peculiar bind of being a term-limited president's vice president. Vance gets credit when things go well, but the proximity that makes him the frontrunner also makes him the nearest target if the administration stumbles. Rubio, operating from Foggy Bottom with a portfolio of foreign crises, carries less domestic political risk.
Early 2028 polling has consistently shown Vance leading the Republican field, but the New Hampshire numbers suggest that lead is softer than it appeared five months ago. The CPAC straw poll earlier this year told a similar story: Rubio came in a close second to Vance in the conservative conference's 2028 presidential nomination vote.
Polls taken two and a half years before a primary are snapshots, not predictions. No votes will be cast in New Hampshire until early 2028, and the field could expand or contract dramatically before then. Rand Paul is reportedly mulling another bid after his 2016 run. Haley and DeSantis both have existing national networks from their 2024 campaigns, even if their current numbers are modest.
But the trajectory matters more than any single data point. In February, Vance looked like a prohibitive favorite. By July, Rubio had closed a 46-point gap to 10. That kind of movement, driven not by a campaign but by the daily work of a cabinet post and a president's public praise, suggests Rubio's appeal is organic rather than manufactured.
Vance has spoken openly about personal adversity in ways that have endeared him to many Republican voters. His policy instincts align closely with the populist wing that dominates the current GOP. He remains the man to beat.
But "the man to beat" and "the inevitable nominee" are very different things. The last Republican who looked inevitable in New Hampshire this far out was Jeb Bush, and the party's voters had other ideas.
When the vice president insists there is no rivalry and the secretary of state pledges his support, take them at their word, but watch what the numbers do. Numbers don't make promises they can't keep.
