GET READY – VANCE AND RUBIO MAKE THE ANNOUNCEMENT
Rubio Is Rising in 2028 Republican Speculation—But the Stronger Evidence Still Points to Vance as the Early Frontrunner
For more than a year, Donald Trump has encouraged one of the most obvious succession questions in Republican politics without answering it.
Would Vice President JD Vance inherit the movement Trump rebuilt around himself?
Or could Secretary of State Marco Rubio, whose standing inside the administration has risen dramatically, emerge as the stronger candidate by 2028?
A new conservative straw poll gives Rubio supporters a reason to argue that the answer is less settled than it once appeared.
But the broader polling record points in a different direction.
Western Journal reported this week that Rubio received 46.1 percent in its weekly presidential straw poll for August 10 through August 16.
Vance finished second at 24.3 percent.
Rep. Thomas Massie was third at 12.7 percent.
Rubio's number rose 2.8 percentage points from the prior week, while Vance gained 2.4 points.
Within that audience, Rubio has clearly built momentum.
The problem is what the poll can actually tell us.
Western Journal describes the survey as non-scientific.
It is a straw poll of people who choose to participate, not a probability-based or carefully weighted sample designed to represent Republican primary voters nationally.
That makes it useful for measuring enthusiasm inside a particular readership.
It makes it much weaker as evidence that Rubio is leading the Republican electorate.
The newest scientific national polling illustrates the difference.
An Echelon Insights survey conducted August 13 through August 17 asked 439 Republican and Republican-leaning likely voters whom they would support if the 2028 Republican presidential primary were held today.
Vance led with 39 percent.
Rubio was second at 22 percent.
Florida Gov. Ron DeSantis received 10 percent and Donald Trump Jr. received 8 percent.
That is a 17-point Vance advantage in a survey fielded during almost exactly the same period as the Western Journal straw poll.
A current compilation of national Republican primary polling also shows Vance ahead.
270toWin's polling average as of August 19 places Vance at roughly 39.8 percent and Rubio at 22.2 percent.
That does not mean the nomination is close to decided.
It does mean the claim that Rubio currently sits at the top of the Republican field depends heavily on which survey is being cited.
Scientific national polls generally still put Vance first.
The race has nevertheless tightened compared with where it stood earlier in Trump's second term.
Emerson College polling in February had Vance at 52 percent and Rubio at 20 percent.
By late May, Emerson found them essentially tied at 36 percent for Vance and 35 percent for Rubio.
A July Emerson survey put the two at 39 percent and 38 percent.
New Hampshire has shown a similar movement.
A University of New Hampshire survey released in July found Vance at 36 percent and Rubio at 26 percent among likely Republican primary voters.
Earlier in the year, Vance had held a much larger lead in the state.
CPAC also showed Rubio making a dramatic gain.
At the conservative conference in March, Vance won the 2028 straw poll with 53 percent while Rubio took 35 percent.
Rubio had received only 3 percent in the previous year's CPAC survey.
So two things are true at once.
Vance remains the early Republican frontrunner by the most recent national polling.
Rubio has become a much more credible alternative than he looked like a year ago.
That distinction is more useful than declaring either man the presumptive nominee more than two years before voting begins.
Rubio's rise is not difficult to explain.
As secretary of state, he has become one of the most visible members of Trump's second-term administration.
He has also taken on national-security responsibilities that give him exposure on war, diplomacy, immigration, Latin America, and major international crises.
Those responsibilities have helped erase some of the distance between Rubio and a Republican base that once viewed him skeptically because of his 2016 rivalry with Trump and his earlier positions on immigration and foreign policy.
Vance has a different advantage.
He is the vice president.
That title gives him a built-in claim to succession that Rubio does not have.
He was Trump's chosen running mate in 2024, has spent the second term building relationships with donors and activists, and has increasingly taken on assignments that mix governing with national political visibility.
Fox News has reported that Vance is serving as finance chair for the Republican National Committee, giving him a direct role in fundraising as the party approaches the 2026 midterms.
That is political infrastructure a secretary of state generally cannot replicate while running American diplomacy.
Rubio has not built an equivalent campaign-in-waiting.
More importantly, he has repeatedly tried to discourage the idea that he intends to challenge Vance.
Rubio has said he has no current plans to run for president in 2028 and that he would support Vance if the vice president enters the race.
That does not create a legally binding promise.
Politicians change their plans.
Events change political calculations.
A bad midterm election, a foreign-policy crisis, a collapse in a candidate's popularity, or a rupture inside the administration could make statements made in 2026 irrelevant by 2028.
But Rubio's public posture is still evidence.
It means the current situation is not best described as two declared rivals fighting for the top spot on a ticket.
Neither man has declared.
Vance is widely expected to consider a run after the midterms.
Rubio has publicly suggested he would defer to him.
Trump is the variable that keeps the rivalry alive.
Earlier this month, The Washington Post reported that Trump told donors during a private Oval Office meeting, "At the end of the day, we need to elect JD."
Fox News independently reported that a source with knowledge of the conversation confirmed the remark.
That is the clearest reported private signal yet that Trump sees Vance as the likely heir.
It is still not a formal endorsement.
The same Washington Post report described Trump continuing to ask people around him whether they preferred Vance or Rubio.
One White House official said Trump polled staff about the two men during a Marine One flight.
Six advisers and allies told the newspaper they were not convinced Trump had made a final decision.
Trump himself then publicly reduced the significance of his private comment.
When reporters asked whether "we need to elect JD" should be understood as an endorsement, Trump said no.
"I think he's great, but we're way too early to even be thinking about that," he said.
That is classic Trump succession politics.
He can favor Vance without surrendering the leverage created by keeping Rubio in the conversation.
He can praise a joint ticket without deciding which man belongs at the top.
And he can privately signal a preference while publicly refusing to make the race official.
There are practical reasons for that ambiguity.
A president who formally anoints a successor too early risks turning himself into a lame duck.
Donors, activists, administration officials, and ambitious Republicans begin organizing around the next center of power.
Trump has little incentive to accelerate that process while he still has more than two years left in office.
The 2026 midterms create another reason to wait.
Vance has invested heavily in Republican fundraising and campaigning.
If Republicans perform strongly in November, he can argue that he helped protect or expand Trump's coalition and congressional majorities.
If Republicans suffer serious losses, critics inside the party could use the result to question whether Vance is capable of carrying the Trump coalition without Trump himself on the ballot.
Rubio could benefit from the second scenario.
He appeals to parts of the Republican donor class and traditional conservative coalition that have never been fully comfortable with Vance's populist economics or his more skeptical approach to foreign intervention.
Axios reported in July that Republican megadonor Ken Griffin told people he would prefer Rubio to Vance in a hypothetical 2028 primary.
Vance, meanwhile, has faced a visible group of conservative critics sometimes described as "Never Vance" Republicans, particularly over foreign policy and the ideological direction of the post-Trump GOP.
That does not mean the anti-Vance faction is large enough to defeat him.
It means Rubio has a potential constituency if a real primary develops.
The policy difference between the two men may eventually matter more than personality.
Vance has built his national identity around a populist version of Trumpism.
He is more skeptical of foreign wars, more openly critical of some traditional Republican economic orthodoxies, and closely identified with the younger MAGA movement.
Rubio came from a more conventional Republican tradition.
He spent years in the Senate developing a hawkish foreign-policy profile and remains more comfortable with many parts of the older Republican national-security establishment.
His service under Trump has narrowed those differences but has not eliminated them.
The Iran conflict has made that tension easier to see.
Vance has generally occupied the more restraint-oriented side of internal Republican foreign-policy debates.
Rubio has been more closely associated with the party's traditional interventionist and strongly pro-Israel wing.
Both men have publicly denied any serious rift and continue to describe each other as friends.
A primary would force distinctions that administration service currently allows them to blur.
That possibility is one reason Trump's idea of a Vance-Rubio ticket sounds attractive to many Republicans.
In June, Trump again said he liked both men and liked them together.
He has described such a pairing as exceptionally difficult for Democrats to beat.
Vance at the top would offer continuity with the MAGA electorate, the vice presidency, and Trump's 2024 coalition.
Rubio could bring foreign-policy experience, stronger relationships with parts of the donor class, and appeal to Republicans who want a less populist or more internationally assertive administration.
On paper, the combination has obvious political logic.
But calling it the likely 2028 ticket goes beyond what is currently known.
Running mates are normally selected after a presidential nominee emerges.
Rubio has not said he wants to serve as Vance's vice president.
The Washington Post reported that even Trump allies who like the joint-ticket idea are uncertain whether Rubio would accept that role.
Rubio would also have reasons to hesitate.
He has already served in the Senate and as secretary of state.
If he believed he had a realistic path to the presidency himself, accepting a second-place position could delay that opportunity for another four or eight years.
At the same time, a Vance presidency could make the vice presidency a logical route to maintaining influence and preserving a future presidential option.
Those calculations are years away.
The polling is much more immediate.
And the polling says something more restrained than the Western Journal result.
Rubio is rising.
Vance is still ahead.
The latest Echelon survey gives Vance a 17-point national advantage.
The current polling average gives him roughly the same margin.
Emerson has produced much closer results, including a virtual tie in July.
New Hampshire shows Rubio gaining ground.
CPAC shows both men dominating the conservative field.
The variation tells us the early electorate is not fixed.
It does not tell us Rubio has overtaken Vance.
Western Journal's straw poll is therefore best treated as evidence of enthusiasm inside a particular conservative audience.
Its 46.1 percent for Rubio may be politically interesting precisely because it differs so sharply from national polling.
It suggests there is a segment of the Republican grassroots that is not prepared simply to accept Vance as the inevitable nominee.
That could matter if the vice president stumbles.
It is not the same thing as a representative poll showing Rubio leads Republican voters nationally.
Thomas Massie's 12.7 percent result reinforces the point.
Massie has a passionate following among libertarian and anti-establishment conservatives, but his standing in broad national Republican primary polling is much smaller.
A self-selected online audience can magnify candidates whose supporters are especially motivated to participate.
That is why scientific polling uses sampling, weighting, and defined electorates rather than simply counting whoever chooses to click.
Even scientific polls at this stage need caution.
The first Republican nominating contests are still far away.
Candidates have not formally entered.
Debates have not happened.
Campaign organizations have not been tested.
Many voters are responding to names and current impressions rather than making the kind of choice they will make after months of campaigning.
Early presidential polling often measures familiarity, office, and media exposure as much as durable support.
Vance and Rubio both benefit from those factors.
They are two of the most visible Republicans in the country after Trump.
That alone helps explain why most current surveys place them above the rest of the field.
Ron DeSantis, Donald Trump Jr., Ted Cruz, Nikki Haley, and other possible contenders remain part of early polling, but none currently combines Vance's institutional advantage with Rubio's recent momentum.
That could change.
The Republican Party has a long history of nominations that looked much less predictable two years before the election than they did by the time voters actually began casting ballots.
The largest unknown is not Rubio's straw-poll number.
It is Trump's endorsement.
For a Republican electorate still overwhelmingly shaped by Trump, his eventual choice could rearrange the race more dramatically than any single 2026 survey.
Vance currently has the stronger claim to that endorsement.
He was Trump's running mate.
Trump has previously called him the most likely successor because he is vice president.
And the president has now been reported telling donors that Republicans need to elect him.
Rubio has the stronger argument that the competition is not closed.
Trump continues to praise him, continues to ask allies to compare the two men, and continues to promote the possibility of a joint ticket.
Rubio's polling has improved enough that donors and activists have a plausible alternative around whom to organize.
That creates a real contest for influence even if it never becomes a contested primary.
The smartest reading of the current evidence is therefore narrower than either side's preferred narrative.
Rubio has not become the Republican frontrunner because he won a Western Journal straw poll.
Vance has not been formally crowned because Trump reportedly told donors to elect him.
The early hierarchy is clearer than the straw poll suggests but less settled than a coronation would imply.
Vance is the current national polling leader.
Rubio is the strongest alternative.
Trump appears to lean toward Vance while intentionally keeping the decision open in public.
And Rubio, at least for now, says he would support Vance rather than run against him.
That makes the most plausible Vance-Rubio scenario very different from a 50-50 contest over who gets the top line.
If the current conditions survive the midterms, Vance would enter the next phase with the natural first claim on the nomination.
Rubio's influence would come from whether he chooses to reinforce that claim, join the ticket, or decide circumstances have changed enough to challenge it.
The midterms may matter more than this week's straw poll.
A Republican victory would strengthen the argument for continuity.
A defeat could open the field.
Trump's public endorsement, whenever it comes, could matter more than both.
For now, the Western Journal result settles only one thing.
Rubio has a substantial and energized constituency inside the conservative movement.
What it does not settle is who Republican primary voters currently prefer.
The newest national evidence still says Vance.

And until Rubio changes his own stated position about supporting the vice president, the question is not yet which one will run at the top of a confirmed ticket.
It is whether the Vance-Rubio rivalry Trump enjoys promoting ever becomes a real race at all.
