Vice President JD Vance, whose star has fallen in recent months after a string of high-profile embarrassments, faces a growing tide of Republicans who are backing Secretary of State Marco Rubio rather than Vance for the 2028 presidential race — despite anonymous White House sources reporting on July 6, 2026, that President Donald Trump had effectively settled on Vance as his preferred successor.
Ken Griffin, a prominent Republican donor who spent over $100 million on the last election, announced during the annual Allen & Company conference in Sun Valley, Idaho, that he is “predisposed” to support Rubio for the 2028 presidential race. Griffin, who is famously anti-MAGA and previously backed Nikki Haley in the 2024 election rather than Trump, revealed his preference to financial journalist Andrew Ross Sorkin. Republican insiders have spoken of a shadow effort to get Rubio elected since early this year.
Vance’s Stumbles and Vulnerabilities
Vance experienced troubled peace negotiations with Iran that he helmed and fumbled initially. In June 2026, he, along with Special Envoy Steve Witkoff and presidential son-in-law Jared Kushner, helped broker a tentative framework aimed at ending the U.S. conflict with Iran. Supporters inside the administration have pointed to the deal as evidence that Vance is ready to operate on the world stage. Critics, however, note that the agreement amounts to a provisional accord rather than a binding ceasefire, and that an earlier round of Iran talks that Vance joined collapsed without result.
Trump has grown irritated with commentator Tucker Carlson, a prominent MAGA voice who has turned sharply critical of the administration over its Middle East policy — a tension that could complicate Vance’s relationship with one wing of the conservative media ecosystem. Pro-Israel conservatives have also expressed frustration over Vance’s role in the Iran negotiations and remarks he made that were seen as critical of Israel’s hard-right political factions.
Anonymous Sources Signal Trump’s Preference
The claim that Trump has chosen Vance over Rubio in the informal competition to inherit the MAGA mantle ahead of the 2028 presidential race follows months of Trump publicly dangling the prospect of a Vance-versus-Rubio showdown. One White House insider said, “POTUS isn’t asking, ‘JD or Marco?’ anymore,” and that Trump has shifted to telling people in his orbit, “JD looks great, right?”
The BBC’s “Americast” program examined the dynamic in an episode published May 11, noting that Trump had been asking advisors whether they preferred “JD or Marco.” Hosts Justin Webb and Anthony Zurcher weighed the respective strengths of each figure: Vance carries greater name recognition nationally, while Rubio could potentially draw Latino voters whose support proved instrumental in securing Trump’s 2024 victory.
Vance Builds a Formidable 2028 Machine
The reported behind-the-scenes endorsement arrives as Vance has assembled an unusually aggressive public profile for a sitting vice president. In June 2026, he published a new memoir, “Communion: Finding My Way Back to Faith,” while simultaneously raising roughly $70 million for the Republican National Committee. Over that same stretch, Vance sat down for more than 30 interviews and is now scheduled for a book tour spanning the next several weeks.
The fundraising numbers have also drawn attention. On June 26, reporting surfaced that Vance had pulled in $4.2 million at a single dinner in Silicon Valley — a figure explicitly tied by sources to an anticipated 2028 presidential run. For a vice president still nearly two years from a potential campaign launch, the pace of activity has been striking.
Rubio’s Allies Acknowledge the Gap
Even those in Rubio’s corner appear to concede that the secretary of state is at a structural disadvantage. One White House source told Axios, “JD is earning it, and Trump sees it,” while a separate insider acknowledged that Rubio “wasn’t planning to run anyway, and he’d be even less likely to do so now.” Rubio himself has repeatedly denied any personal ambition for the Oval Office and has said publicly that he would support Vance if the vice president enters the race.
A viral video involving Rubio, which surfaced in the weeks before the BBC episode aired, had already rekindled public speculation about the party’s 2028 direction — underscoring how closely political observers have been watching both men.
Trump Keeps His Options Open
Despite the insider chatter, Trump has dodged direct queries on the subject for months. On June 3, he told the New York Post that Vance and Rubio are “both great” and that there is “a long time left” before 2028 becomes a live question. Some political analysts have suggested he has strong incentives to keep the race open; a definitively anointed heir could, in theory, begin to overshadow Trump within his own administration.
Reporting in February made precisely that argument, though it was accompanied by quotes from five separate sources cautioning against interpreting Trump’s hesitation as any sign of diminished enthusiasm for Vance. The pattern — anonymous endorsements of Vance paired with public presidential silence — has now repeated itself several times.
Meanwhile, Democrats are facing their own structural headaches ahead of the November midterm elections. The party suffered setbacks in two separate federal court cases — one in Virginia and one in Louisiana — within 10 days, delivering what analysts described as a significant blow to Democratic hopes of recapturing Congress. The Democratic candidate for the Senate from Maine, Graham Platner, who had been seen as a tough opponent for Sen. Susan Collins, had to withdraw last week from the running due to a rape accusation.
Whether Trump’s preference hardens into an official blessing remains to be seen. For now, the whisper campaign appears to be working in the vice president’s favor.
