Secretary of State Marco Rubio now outperforms Vice President JD Vance in three hypothetical 2028 presidential match-ups against leading Democrats, an Emerson College survey finds, even as the White House insists no rivalry exists.
The Emerson College/The Hill poll, conducted August 16, 17 among 1,000 registered voters with a margin of error of plus or minus three points, tested both Republicans against a roster of potential Democratic nominees. Rubio beat former Vice President Kamala Harris 48 percent to 43 percent. Vance, by contrast, trailed Harris by four points.
The gap held against New York Congresswoman Alexandria Ocasio-Cortez. Rubio topped her by the same 48-to-43 margin, while Vance managed only a two-point edge, 46 to 44, within the poll's margin of error. Against California Governor Gavin Newsom in a California-specific test, Rubio kept the deficit to two points, 46 to 48. Vance fell behind Newsom by five, 44 to 49.
Two Democrats beat both Republicans. Former Transportation Secretary Pete Buttigieg led each man 49 to 44, and Georgia Senator Jon Ossoff held a three-point edge over Rubio and a five-point lead over Vance. Buttigieg has been actively campaigning for Democrats in key 2026 midterm contests, building a national profile that could translate into a primary bid.
The Emerson numbers do not exist in a vacuum. A separate University of New Hampshire poll reported by Fox News found Rubio surging among likely Republican primary voters in New Hampshire, climbing from 7 percent in February to 26 percent, while Vance slipped from 53 percent to 36 percent. The gap that once looked insurmountable has narrowed to single digits in a state that holds outsized influence in presidential primaries.
Fox News attributed Rubio's rise to his elevated public profile as the nation's top diplomat and to repeated praise from President Trump, who has called Rubio potentially "the greatest secretary of state in history" and promoted a Vance-Rubio ticket as "unstoppable."
An operative in Trump's political orbit told Fox News that "Vice President Vance is the future of the Republican Party, and Marco Rubio is one of his closest friends in the administration." But a longtime Republican strategist offered a blunter assessment:
"Vance is in the catbird seat until something really goes bad, and Trump is going to blame him."
That kind of frank talk from party insiders suggests the 2028 field is far more fluid than the White House wants to acknowledge.
White House spokeswoman Anna Kelly responded to the Daily Mail's inquiry with a pointed dismissal of the entire premise:
"Why is the legacy media obsessed with driving a wedge between Vice President Vance and Secretary Rubio that does not exist? There is one camp, President Trump's camp, and the entire administration is working together to execute the President's agenda."
Trump himself has publicly described Vance as "great" while adding that it is "way too early to even be thinking about" an endorsement. Earlier in August, The Washington Post reported that behind closed doors, Trump told donors "at the end of the day, we need to elect JD" in 2028, a private signal that cuts against the public posture of studied neutrality.
As Just The News noted, the margin of error makes the polling differences between Rubio and Vance statistically comparable in several of the tested match-ups. Speculation about a Rubio candidacy has grown, but neither man has announced any intent to run, and by all public accounts their working relationship remains strong.
The poll results cut both ways. Buttigieg's identical 49-to-44 advantage over both Rubio and Vance makes him the strongest Democratic performer tested, and his midterm trail work suggests he is building the kind of national infrastructure a presidential campaign requires. Ossoff, meanwhile, posted competitive numbers despite making headlines just days before the poll for hinting at a romantic link between President Trump and White House aide Natalie Harp, a provocation that did nothing to dent his standing with voters in the survey.
Harris, the defeated 2024 Democratic nominee, still led Vance by four points but trailed Rubio by five, a spread that raises questions about whether Democrats would be wise to turn the page from their 2024 standard-bearer. Ocasio-Cortez trailed both Republicans, though her deficit against Vance was narrow enough to fall inside the margin of error.
For a party still sorting through its post-2024 wreckage, the numbers offer no clear front-runner. Buttigieg and Ossoff performed best, but neither has been tested by the full weight of a presidential campaign. Harris carries the baggage of a lost general election. Ocasio-Cortez energizes progressives but underperforms in a national electorate.
Polls taken more than two years before an election are snapshots of name recognition and mood, not predictive instruments. The Emerson survey sampled registered voters, not likely voters, a broader universe that can shift dramatically as a race takes shape. And with a margin of error of three points, several of these match-ups are effectively tied.
Still, the trend lines matter. Rubio's trajectory, from a single-digit afterthought in February's New Hampshire primary polling to a competitive figure nationally, reflects something real. A Secretary of State who negotiates on the world stage commands media attention that a Vice President, tethered to ceremonial duties and Senate tie-breaking votes, often does not. Whether that visibility translates into durable primary support is an open question, but the data shows it is translating into general-election competitiveness right now.
The White House can dismiss the polls as media mischief. Republican voters may eventually do the same. But the numbers say what they say: Rubio runs stronger against every major Democratic contender tested except Buttigieg, where both Republicans lose by the same margin. That is not a wedge invented by reporters. It is arithmetic.
If the GOP wants to hold the White House in 2028, the question is not whether Rubio and Vance get along. It is which one gives the party the best chance to win, and right now, the early data points in one direction.
