President Trump has spent more than a year privately polling advisers, dinner guests, and even crowds of law enforcement officers on a single question: JD Vance or Marco Rubio? The answer, so far, is that he refuses to give one, and that calculated ambiguity is shaping the earliest contours of the 2028 Republican presidential primary.
Vice President Vance leads Secretary of State Rubio by a single point, 36 percent to 35 percent, in an Emerson College survey of Republican voters released in May, a gap well within the poll's 4.7-point margin of error. The numbers confirm what anyone paying attention already senses: this is a dead heat on paper, even if the two men occupy very different positions in practice.
Vance holds the vice presidency, the RNC's chief fundraiser title, and a growing public portfolio that now includes high-profile Iran negotiations and a new book tour. Rubio commands the State Department and Trump's ear on international affairs. Both men say they are focused on their current jobs. Neither is acting like it.
At a recent Rose Garden dinner with law enforcement officers, Trump turned the room into an informal focus group. "Who likes JD Vance? Who likes Marco Rubio?" he asked. "Alright, sounds like a good ticket." Then came the kicker: "That does not mean you have my endorsement under any circumstance."
That scene, captured on video and reported by Fox News, distills Trump's approach. He has publicly called Vance and Rubio a "dream team" and an "unstoppable ticket" for 2028, but he has pointedly declined to say who should sit at the top. Nearly a dozen sources close to the White House, most speaking anonymously, told USA TODAY that Trump has been running this informal survey for at least a year, in the Oval Office, at Mar-a-Lago, and at social events.
Republican strategist Matt Gorman framed the dynamic plainly: "I don't expect, candidly, Trump to, the day after the midterms, anoint Vance." He added: "Vance will go out, and he'll earn it."
The strategy appears designed to keep both men performing at peak intensity. Sources described Trump as focused on who has the best chance of winning, while also keeping Vance "on his toes and motivated to deliver." For a president who built a television empire on competition, the instinct is familiar.
Whatever Vance says publicly about not thinking about a job "years down the road," his calendar tells a different story. He traveled overseas to meet with Iranian leaders, held a news conference in Switzerland, and drew immediate praise from Trump on June 22.
"I thought JD Vance this morning was fantastic. I watched his news conference from Switzerland. He's a very smart guy. He did a great job."
Five days earlier, on June 17, Trump had quipped that if the Iran deal goes sideways, it would be Vance's fault, a remark that carried both humor and a clear signal that Vance now owns a piece of the administration's most consequential foreign policy gamble.
Vance is also promoting his new book, "Communion," which extends the personal narrative he built with "Hillbilly Elegy" into explicitly political and religious territory. In it, he backs state-level bans on businesses being open on holidays like Thanksgiving so workers can be with their families, a position that blends the economic populism and religious conservatism he told USA TODAY are not in conflict.
"I don't think economic populism is somehow inconsistent with religious conservatism. I would say the tradition of the Christian church is very supportive of a particular kind of economic populism."
He has also told USA TODAY he supports the right of workers to privately unionize and bargain for higher wages. For a man who worked at a San Francisco investment firm before entering politics and converted to Catholicism not long before running for office, the ideological journey has been dramatic. Whether voters read it as authentic conviction or political positioning will matter enormously in a primary.
As RNC chief fundraiser, Vance already has a structural advantage no rival can match. He is exempt from the law restricting other federal officials' political activity, and the fundraising role puts him in front of donors and party operatives across the country. GOP consultant Mike DuHaime, a former RNC political director, put it simply: "By virtue of his official position, Vance is a major player without having to announce. He can wait longer than anyone else."
Rubio has publicly said he wants to stay at the State Department through the end of Trump's term and has indicated he won't run if Vance does. But unnamed insiders told USA TODAY that his actions tell "a different story." He took the White House podium in May, a move that put him in front of cameras in a setting usually reserved for the president or vice president.
The former Florida senator and 2016 presidential contender remains one of Trump's most trusted advisers on international affairs. That proximity matters. While Vance was holding down the White House during one stretch, Trump traveled to China with Rubio, a dynamic that underscored the secretary of state's access to the president on the world stage.
Vance, when confronted with the speculation, has deflected with discipline. At a fraud press conference, he said he didn't think "it sounds like the president of the United States to have a televised competition for who would succeed him as his apprentice." The line was sharp enough to land without sounding defensive, and careful enough to avoid crossing Trump.
At Trump's June 24 rally on the National Mall, USA TODAY interviewed voters whose views tracked the broader polling: warm toward Vance, open to Rubio, and ultimately loyal to Trump's judgment.
Vicki Schwartz, a 70-year-old suburban Columbus resident who first voted for Vance in Ohio and was two chapters into "Communion," offered a characteristically practical solution: "I kind of feel like they should flip a coin, and then whoever wins the coin flip, that one runs for president, or gets first choice."
Nasim Nabily, a 43-year-old business owner from Landover, Maryland, drew a distinction that may define Vance's pitch to the broader electorate. Vance is "not as hard-hitting as Trump," Nabily said, "but he's a little more articulate." That assessment, less force, more polish, could be a strength or a liability depending on whether the 2028 primary rewards continuity or intensity.
Paul Ayers, a 73-year-old retired real estate agent from Phoenix, was more direct: "I think I'm going to go with Vance no matter what." He said that even in the context of whether Trump's endorsement would change his mind. Logan Hottell, an 18-year-old recent high school graduate from Stanton, Virginia, said he was inclined toward Vance and wanted to learn more, the kind of soft support that a campaign infrastructure can harden over time.
The early-state activity has already begun. Vance has made appearances that carry unmistakable 2028 overtones, even as he insists his focus remains on the vice presidency.
Vance and Rubio are not the only names circulating. Three sources close to the White House told USA TODAY that Sen. Ted Cruz is considering a 2028 run. Cruz declined to comment. And Trump's endorsement power, while still formidable, showed cracks when his pick for Iowa governor, Randy Feenstra, lost the Republican primary to a candidate backed by Turning Point USA.
That result matters for Vance. If Trump's endorsement carries less weight in contested primaries, the vice president's strategy of waiting for a blessing from Mar-a-Lago becomes riskier. A Trump nod might not clear the field the way it once would have.
Vance's media appearances have drawn attention from unexpected quarters. He appeared on "The View" in June and has conducted interviews tied to both the Iran negotiations and his book, a dual-track approach that lets him project both policy seriousness and personal depth.
When asked about timing, Vance told USA TODAY he would huddle with his wife Usha after the midterms. "I just haven't really thought that much about it," he said. That is the kind of statement that is either perfectly honest or perfectly calibrated. In presidential politics, the two are rarely distinguishable.
The broader picture is one of a Republican Party that has internalized Trump's political style but has not yet settled on who carries it forward. Vance represents one version, the Appalachian populist who talks about workers' rights and religious conviction with equal comfort. Rubio represents another, the polished foreign-policy hand who ran for president a decade ago and never stopped wanting the job.
Trump, characteristically, seems to enjoy the tension. He praises Vance's Switzerland performance one week and jokes about blame the next. He floats a joint ticket without specifying who leads it. He tells a room full of cops the pairing sounds great, then immediately yanks back the endorsement.
Even commentators outside the conservative movement have taken notice of Vance's positioning, a sign that his profile now extends well beyond the MAGA base.
The internal dynamics of the Trump White House have always rewarded performance under pressure. Vance appears to understand that. His public posture is deference. His operational posture is preparation.
In the end, the 2028 Republican primary may come down to a question Trump has been asking for a year, Vance or Rubio?, and one he has not yet bothered to answer. The fact that he keeps asking tells you he already knows the answer matters. The fact that he won't share it tells you he wants both men to keep earning it.
That's not indecision. That's management. And in Trump's Republican Party, the audition never really ends.
