Vance crushes Rubio in a 2028 poll, but nothing is settled

Introduction: a number that hits hard before the race even begins

35.4% versus 16.5%, the gap everyone is talking about

U.S. Vice President JD Vance dominates the potential Republican field for the 2028 presidential election, according to a new national poll released this week. The Big Data Poll gives him 35.4% support among potential Republican candidates, more than double that of Secretary of State Marco Rubio, second with 16.5%.

This figure, impressive as it is, comes in a political context where the election remains more than two years away and no candidate has yet formally announced a run. But in American politics, two years is already an eternity, and starting positions matter.

A poll that confirms an underlying trend

This is not an isolated statistical fluke. For months, Vance has led nearly every internal Republican poll, with varying margins depending on the pollster, but one constant: he consistently outpaces Rubio, Florida Governor Ron DeSantis, and the rest of the conservative field.

On the Democratic side, Kamala Harris leads with 29.1%, followed by California Governor Gavin Newsom at 15%, confirming that the former vice president remains, for now, the standard-bearer of the progressive camp despite her 2024 defeat.

What the Big Data Poll actually shows

A robust methodology despite the distant horizon

The poll was conducted from June 26 to 28, 2026, among 1,261 registered Republican voters, with a margin of error of 1.8%, a sample large enough to give these results weight despite the volatile nature of polling this far ahead of an election.

Among voters deemed likely to vote, Vance's lead widens even further: 36.6% versus 17.5% for Rubio, a gap of nearly twenty points that far exceeds the poll's statistical margin of error.

A fragmented Republican field behind the two frontrunners

Behind the top duo, the rest of the potential Republican field already looks left behind: Governor Ron DeSantis gets 7.1%, Health Secretary Robert F. Kennedy Jr. gets 6.5%, and Texas Senator Ted Cruz tops out at 4.4%. Every other potential candidate remains below 4%.

12.1% of respondents remain undecided, while 2.5% would prefer someone outside this list, a sign that despite Vance's dominance, a meaningful part of the conservative base is still looking for an alternative.

Vance dominates across every demographic category

Support that cuts across men and women alike

One of the most striking elements of the Big Data Poll is the sheer breadth of support for Vance. He leads Rubio among both men and women, a relative feat for a vice president often associated with a tougher, more masculine image of American conservative politics.

This cross-cutting support contradicts the idea that Vance appeals only to a narrow slice of the male or rural Republican electorate; the numbers instead show a broad, diverse base of support across the party's major demographic categories.

A confirmed lead among Hispanics and independents

Vance also leads Rubio among Hispanic voters, a notable result since Rubio, of Cuban descent, had long been seen as the Republican Party's natural asset for winning over this strategically important and growing demographic.

The lead also holds among independent voters, a group often decisive in general elections, suggesting that Vance's potential could extend beyond the Republican primary alone and into a future general election.

Vance's persistent hesitation waltz

"I'll eventually have to make that decision"

Despite these impressive numbers, Vance continues to publicly play it cautious about his intentions for 2028. Asked by journalist Megyn Kelly last month, he said: "Yes, after the midterm elections, I'll eventually have to make that decision," a carefully calibrated line that commits him to nothing concrete.

On CBS Sunday Morning, alongside Second Lady Usha Vance, he added: "I have no doubt that the president of the United States will be very supportive of whatever I ultimately decide to do," while acknowledging: "But we really haven't discussed yet what that thing will be."

A calculated caution in the face of public opinion

Last May, after Trump called a potential Vance-Rubio ticket a "dream team," Vance himself warned about the negative image a vice president would project if he were "barely a year and a half into the job and already eyeing another one two and a half years down the road."

He added soberly: "There are few subjects I want to talk about less," a line that captures well the tension between obvious presidential ambition and the political need to appear focused on his current duties rather than his next career move.

Rubio ready to step aside for Vance, according to the Associated Press

Repeated confidences to close advisers

According to information reported by the Associated Press and relayed by RBC-Ukraine, Rubio will not seek the Republican nomination in 2028 if Vance announces he is running. The Secretary of State reportedly told his advisers and inner circle on several occasions that he intends to step aside for the vice president.

Rubio himself reportedly told Vanity Fair in an interview: "If J.D. Vance runs for president, he'll be our candidate, and I'll be one of the first to support him," a public statement that confirms the private confidences reported by the Associated Press.

A quiet rivalry despite declarations of loyalty

This apparent deference has not stopped Rubio from methodically building his influence within the administration, notably by placing close allies in key positions on the White House's National Security Council, including former State Department adviser Mike Needham, now deputy national security adviser.

According to diplomat Ian Kelly, quoted by the Associated Press, Vance and Rubio harbor equal presidential ambitions despite their public statements of withdrawal, hinting at a quiet but very real rivalry at the top of the Republican Party.

Foreign policy divergences between the two rivals

Israel, Lebanon, and internal fault lines

Beyond the presidential race, Rubio and Vance are taking different approaches to implementing President Trump's foreign policy and defense agenda. Rubio maintains steady support for Tel Aviv or refrains from commenting on the situation in Lebanon, while Vance has repeatedly criticized Israel's actions in that country.

This divergence, quiet but real, illustrates the internal tensions running through the Republican administration over major foreign policy directions, particularly sensitive in a Middle East region that remains volatile and explosive.

Rubio's skepticism toward negotiations with Iran

The Secretary of State proved so skeptical about the possibility of reaching an acceptable deal with Tehran that he refused, last April, to lead the American delegation at talks held in Pakistan, preferring to invoke Ronald Reagan's doctrine on the importance of the "free world."

According to Ian Kelly, should negotiations with Iran fail, Vance could bear the political consequences with respect to a potential presidential nomination, a scenario that shows just how much current foreign policy already weighs on the succession calculus for 2028.

The volatile track record of 2028 polls over the past year

Dramatic swings that vary by pollster

The recent history of 2028 polling illustrates impressive volatility. An Emerson College poll from June 2025 had Vance at 46% against just 12% for Rubio. An AtlasIntel poll from May 2026 even showed a dramatic reversal, putting Rubio ahead with 45.4% versus 29.6% for Vance, before the trend swung back in the vice president's favor in subsequent polls.

An Emerson College poll from late May 2026 even showed the two men in a near-tie, 35.5% for Vance versus 34.6% for Rubio, before the latest Big Data Poll dramatically widened the gap once again.

An unstable landscape that calls for analytical caution

This methodological and temporal instability across pollsters is a reminder of a fundamental rule of political analysis: no single poll, however impressive, should be read as a firm prediction of an election result that remains more than two years away.

Political analysts themselves acknowledge that these early polls mostly measure name recognition and each candidate's current standing within their party, rather than a genuine prediction of the future Republican or Democratic nominee.

Trump and the presidential shadow looming over the race

The president floats an "unbeatable ticket"

President Donald Trump himself has fueled speculation by suggesting, in an interview aired on a podcast, that a Vance-Rubio ticket would be "unbeatable" in 2028, a public statement that implicitly places his seal of approval on the two leading contenders to succeed him.

This presidential intervention, far from trivial, strengthens Vance's position while carefully avoiding a public choice between the two men, a classic Trump political strategy of keeping his lieutenants locked in perpetual competition for his approval.

The weight of the Trump legacy on the conservative electorate

A Yale Youth Poll also revealed that if Trump himself appeared on the hypothetical 2028 ballot, he would completely dominate the field, including Vance, with 50% support against just 19% for the vice president, a blunt reminder that the president's personal aura remains, for now, unmatched within the Republican Party.

This data point illustrates a fundamental reality: the 2028 Republican primary will largely be decided by each candidate's ability to present themselves as the legitimate heir to Trumpism, rather than as a distinct alternative to the current presidential line.

The Democratic camp faces an equally fragmented field

Harris leads, but far from a crushing dominance

On the Democratic side, Kamala Harris retains a lead in most recent polls, but with margins far more modest than those seen for Vance. The Big Data Poll gives her 29.1%, followed by Newsom at 15%, a real but far less dramatic gap than the current Republican dominance.

Other Democratic figures, including former Transportation Secretary Pete Buttigieg and New York Representative Alexandria Ocasio-Cortez, continue to draw measurable support, a sign of a Democratic Party still unable to coalesce around a single figure after its 2024 defeat.

A fragmentation that could benefit Republicans

This persistent fragmentation of the Democratic field, in contrast with the rapid consolidation of Republican support around Vance, could give the conservative party a considerable strategic advantage heading into 2028, provided this Republican unity holds up over time and through the upcoming midterms.

It remains to be seen whether a Democratic candidate, whether Harris, Newsom, or an emerging figure still little known to the general public, can unify the party enough to pose a credible electoral threat to the Republican ticket taking shape.

What this race reveals about the future of Trumpism without Trump

A real-world test for the MAGA movement

This early clash between Vance and Rubio is, in reality, a real-world test of whether the MAGA movement can survive once Trump eventually leaves the active political stage. The fundamental question is no longer just who wins the primary, but whether Trumpism can survive institutionally without its charismatic founder.

Vance, as the most direct ideological heir to Trump's populist and protectionist line, appears better positioned to carry that torch than Rubio, whose background as a traditional foreign policy hawk aligns him more closely with the Republican Party's establishment wing.

A worrying signal for the future of Western geopolitics

For the West and its allies, with Ukraine on the front line against Russian aggression, this succession race is not simply an internal American political exercise: it will determine who directs American foreign policy at a critical moment when the war against Vladimir Putin's Russia could still shape the global balance of power for decades.

A more isolationist Vance, skeptical of foreign military aid, legitimately worries allied capitals, while a more traditionally interventionist Rubio would offer Western partners greater reassurance about the continuity of American support against the combined threats of Russia, China, Iran, and North Korea.

The midterms as a springboard

2026, the real test before 2028

Vance himself has repeated that he will wait for the results of the 2026 midterm elections before making a formal decision about 2028, a cautious strategy that lets him gauge how his association with the Trump administration affects his personal popularity before fully committing.

A poor Republican showing in the midterms could weaken his position as the natural frontrunner, while a solid party victory would considerably strengthen his legitimacy as the designated heir to the Trumpist coalition.

The risky calculus of political patience

This waiting strategy, however, carries its own risks: by refusing to clarify his intentions too early, Vance also leaves an open window for Rubio or other contenders to build their own fundraising and support networks before the race truly accelerates after the midterms.

American politics rarely rewards prolonged indecision, and Vance will sooner or later have to choose between his current strategic caution and the need to mobilize the considerable financial and organizational resources required for a national presidential campaign.

The weight of money and fundraising networks

Billions already at stake for 2028

According to some estimates cited in media coverage of the race, combined spending on the 2028 presidential primary could exceed $5.3 billion, a staggering sum that underscores the scale of the financial stakes already in play well before the first official vote.

Vance, as the sitting vice president, enjoys privileged access to major Republican donors and the party's traditional fundraising networks, a considerable structural advantage over Rubio despite his own well-established network within the conservative establishment.

Prediction markets confirm the trend

Prediction market platforms like Polymarket also reflect this fluctuating dynamic, with odds swinging between the two men over the months depending on recent political and diplomatic developments, including negotiations with Iran and internal tensions over American foreign policy.

These markets, while imperfect as predictive tools, offer an additional real-time barometer of public perception of the race, often more responsive to daily news than traditional polls conducted at spaced intervals.

What this rivalry signals for tomorrow's foreign policy

Two visions of America's role in the world

Beyond the numbers and the polls, this Vance-Rubio rivalry represents a fundamental choice for the future of American foreign policy: on one side, a more isolationist vision skeptical of prolonged foreign military commitments; on the other, relative continuity with the Republican Party's traditional interventionism against global authoritarian threats.

This choice will have direct repercussions on crucial issues like continued support for Ukraine against the Russian invasion, firmness toward Iran's regional ambitions, and America's posture toward Chinese military expansion in the Pacific.

The West watches with legitimate concern

Allied capitals from Washington to Kyiv, Brussels, Tokyo, and Seoul are following this succession race with particular attention, aware that the outcome of this Republican primary could profoundly reshape Western security architecture for the coming decade.

In a world where Russia, China, Iran, and North Korea increasingly coordinate their strategic interests against the Western-led international order, the choice of the next Republican American leader is never a simple domestic political exercise.

The historical precedent of vice presidents inheriting the party

George H.W. Bush, a rare model of success

Recent American political history offers few examples of vice presidents successfully converting their position into a direct presidential victory. George H.W. Bush remains the most emblematic case, succeeding Ronald Reagan in 1988 after two terms as vice president, a trajectory Vance clearly hopes to replicate.

Other vice presidents, such as Al Gore in 2000 or Hubert Humphrey in 1968, failed in their bid for succession despite favorable starting positions, a reminder that the structural advantage of the office never automatically guarantees the final victory.

Vance facing the weight of this mixed track record

This historical lesson should prompt caution in anyone who considers Vance's 2028 victory a foregone conclusion, despite his current comfortable lead in internal Republican Party polls over Rubio and the rest of the conservative field.

The real test for Vance will not simply be maintaining his lead in primary polls, but converting that internal popularity into a national electoral coalition capable of winning against a Democratic candidate in the 2028 general election.

Conclusion: a solid lead, but a future that remains uncertain

Vance dominates today, but recent history calls for caution

The Big Data Poll confirms, once again, JD Vance's dominant position in the 2028 Republican race, with a lead that far exceeds the statistical margin of error and shows up in nearly every demographic category measured by pollsters.

But the recent track record of these same polls, marked by dramatic reversals between Vance and Rubio depending on the pollster and the period, is a reminder that no lead is irreversible more than two years before a presidential election, particularly in as volatile an American political climate as that of 2026.

The real stakes go far beyond the numbers

In the end, what really matters is not the exact percentage Vance or Rubio gets in any given monthly poll, but the geopolitical vision the future Republican nominee will carry for America and its Western allies against the combined challenges of Russia, China, Iran, and North Korea.

Whether it's Vance, Rubio, or a still-unexpected figure who emerges before 2028, the future of Western leadership in a world increasingly threatened by authoritarian regimes will largely depend on this choice, and the entire world, Ukraine foremost among them, would do well to pay close attention starting now.

Columnist's transparency note

My limits and my acknowledged biases

I write this column with an openly acknowledged concern about the possibility of a future Republican leadership less committed to military support for Ukraine, which inevitably colors my analysis of the rivalry between Vance and Rubio on foreign policy issues.

I also acknowledge that I am not a specialist in electoral polling methodology, and that my interpretation of the numbers relies on analyses already published by the pollsters and specialized media cited in this article.

What I don't know, and my method

I cannot predict with certainty who will win the 2028 Republican primary, nor whether Vance will maintain his current lead through the midterm elections and beyond; the recent history of polling shows real volatility that calls for analytical humility.

My method relies on cross-referencing several independent polls conducted by different institutes, as well as reporting from the Associated Press and other specialized media on the internal dynamics between Vance and Rubio.
