Vice President JD Vance's allies are quietly preparing for a contested 2028 Republican presidential primary as a growing roster of GOP senators makes early moves toward challenging Trump's heir apparent.
Ted Cruz traveled to Iowa. John Kennedy followed him there. Rick Scott showed up at a Republican dinner in New Hampshire. And behind the scenes, Vance's own team has begun gaming out a primary fight that, just months ago, many in the party assumed would never materialize. The Daily Mail reported that Vance aides are privately bracing for a bruising contest, even as the vice president works to shore up support among key Republican constituencies.
The jockeying comes at a moment when Vance's standing inside the party, once treated as a near-lock for the nomination, has shown real cracks. A Bowling Green State University/YouGov poll of GOP voters put Vance at 44 percent, with Secretary of State Marco Rubio at 21 percent, Cruz at just 3 percent, and Kentucky Senator Rand Paul at 1 percent. Those top-line numbers look comfortable. But prediction-market data from Kalshi tells a rougher story: Vance's odds slid from 43 percent in February to 31 percent in June before recovering to 45 percent. During that same stretch, Rubio's odds surged to 30 percent before settling back to 21 percent.
No potential challenger has been more direct than Cruz. On the Pod Force One podcast, the Texas senator framed the coming primary as a fight over the Republican Party's identity:
"Are we a small-government, free-market conservative party, or are we a big-government nanny-state party? That's a really big, fundamental divide about what we believe... On foreign policy, are we an isolationist party? Do we want to just withdraw from the world? Or do we believe in American leadership?"
Cruz did not name Vance in that exchange. He did not need to. The vice president's publicly expressed doubts about the Iran strikes and his well-known friendship with Tucker Carlson have made him the obvious target of that framing. And Cruz has been far less subtle in private. Axios obtained secretly recorded audio from 2025 donor meetings in which Cruz accused Vance of being a Carlson "protégé" and said the pair were "one and the same."
That line of attack carries weight in certain Republican circles. Carlson has faced allegations of anti-Semitism tied to his criticism of the Iran war, and the association has become a vulnerability for Vance among Jewish conservative donors, a group the vice president is now working hard to court.
Vance flew to Las Vegas at the end of August to address the Republican Jewish Coalition summit. After missing Jewish conservative radio host Sid Rosenberg at that event, he invited Rosenberg to the White House. On Friday, Vance hosted a Shabbat dinner at the Naval Observatory ahead of Yom Kippur. The outreach is deliberate. Vance's role as RNC finance chair gives him regular access to the party's biggest donors, and he appears to understand that holding the inside lane requires more than a title.
Louisiana Senator John Kennedy, 74, has built a national profile through his Fox News appearances and his folksy one-liners. He is not pretending to rule anything out. The Washington Post quoted Kennedy putting it plainly:
"I'm planning on running for reelection. But if I get tired of this place and/or if a bunch of goobers run for president, then I reserve the right to run."
He added, channeling the Judds: "What was that song that the Judds sang, 'Why Not Me?'"
Kennedy's Senate campaign account held $18.6 million at the end of June, a war chest that gives him options. He authored a 2025 bestseller and spoke at a major Republican gathering in Iowa on Saturday, the state that holds the first GOP nominating contest. Cruz traveled to Iowa as well. Neither man is acting like someone content to watch from the sidelines.
Rick Scott, one of the wealthiest members of the Senate, attended a GOP dinner in New Hampshire on Friday. He insists he is not running. But his remarks at the dinner carried a certain ambition. Scott told attendees: "The best job is to be the president. If that's not available, be the governor. If that's not available and you still have to do something, maybe be a US senator." That is not how a man with no interest in higher office talks.
Rubio has said he has no plans to run and would back Vance. He lacks a political machine or network of aides built around a 2028 campaign. But the polling suggests he would be Vance's most formidable opponent if he changed his mind. An Emerson poll in May showed Rubio just one point behind Vance. A recent analysis of hypothetical match-ups underscored how competitive that race could become.
The donor class is watching. Citadel billionaire Ken Griffin, who gave more than $100 million to Republican-aligned groups during the 2024 cycle, said in July he would be "predisposed" to back Rubio over Vance. That kind of money does not sit idle. If Rubio signals even mild interest, the financial infrastructure for a serious challenge could materialize fast.
Trump himself has acknowledged the daylight between his position and Vance's. After launching strikes in late February, the president publicly conceded that Vance was "maybe less enthusiastic" about the action. In March, Trump told reporters that Vance was "philosophically a little bit different than me," though he insisted the pair "get along very well on this." Those comments were measured, but they gave every potential rival a talking point, and Cruz, in particular, has seized on it.
Rand Paul told the Washington Post he is "50-50" on a run and will not decide until after the midterms. His confidence, at least, is not lacking: "I think the Republican primary electorate's probably more with me than with the rest of them." His 1 percent showing in the Bowling Green/YouGov poll suggests otherwise, but Paul has always been more interested in moving the debate than winning the horse race.
Kentucky Congressman Thomas Massie, who lost his May primary to a Trump-backed challenger, has not ruled out a run either. His assessment of the landscape was characteristically blunt: "Maybe we lose the majority, everybody's down on Trump, then he gets impeached three times and everybody likes him again. Who knows?" Massie's point, that the political terrain will look completely different after the midterms, is the one thing every potential candidate agrees on.
A McLaughlin survey from last month showed Vance at 32 percent and Donald Trump Jr. at 19 percent, a reminder that the field could expand well beyond the Senate. Vance still commands the strongest position in early polling, but commanding and comfortable are not the same thing.
The vice president's challenge is not that Cruz or Kennedy or Scott can individually overtake him. It is that the combined maneuvering signals a party that has not consolidated behind him, and may not intend to. The Iran war exposed a genuine ideological fault line on foreign policy. Vance's skepticism put him at odds with the interventionist wing, and Cruz has turned that gap into a campaign pitch before any campaign officially exists.
Meanwhile, the question of Tucker Carlson's influence on the right continues to complicate Vance's positioning. Cruz's privately recorded attacks linking Vance and Carlson were clearly designed for donor ears, and the fact that they leaked suggests someone wanted them public. Vance's aggressive outreach to Jewish conservatives, the RJC summit, the White House visit, the Shabbat dinner, reads as a direct response to that vulnerability.
Usha Vance has signaled openness to a 2028 run while stressing that the family's focus remains on the midterms. That is the disciplined answer. But discipline only works if the field cooperates, and right now, the field is doing the opposite.
Being the front-runner two years out is a fine position. Being the front-runner everyone else is already organizing against is a different one entirely.
