Until late 2025, the Republican Party seemed poised to carry its MAGA coalition intact into the 2028 presidential election. No successor could replicate Trump’s political style or personality, but the coalition he built—working-class voters, growing numbers of Latinos and former Democrats like Robert F. Kennedy Jr. and Tulsi Gabbard—appeared resilient.
JD Vance emerged as the likely frontrunner for the 2028 nomination. Marco Rubio, the only other candidate with broad national support, had pledged to endorse Vance if he ran. The race seemed less like a contest than a succession plan.
However, the right wing is far from united. While much of the base may align with Vance’s instincts, his victory in an open primary cannot be guaranteed.
My prior analysis in JD Vance and the Future of the Republican Party suggested Vance would declare around the 2026 midterms and Rubio would back him. A few marginal candidates might enter, but none reached double digits. That scenario remains possible but is no longer certain.
Two developments have shifted the balance: a bitter right-wing dispute over U.S.-Israel relations and the Iran war.
The first issue has not directly involved Vance but fractured the political landscape he must navigate. Far-right podcasters and pundits had long focused on Israel and Jews. This debate moved from fringe to mainstream after Tucker Carlson interviewed Nick Fuentes in October 2025—just one month following Charlie Kirk’s assassination. Influential voices now entertain conspiracy theories that Jewish groups threaten America.
The conservative movement has always been diverse, with libertarians, social conservatives, anti-communist liberals, nationalists, and other factions competing under the Republican banner. But over the past nine months, positions on Israel, American Jews, and media personalities have become loyalty tests. Conservatives increasingly split into camps and excommunicate dissenters.
Every presidential nominee must unite competing factions. Vance faces an unusual challenge because he entered politics through conservative intellectual circles, think tanks, and media. He has allies across rival camps. Preserving those relationships without appearing subservient to any faction may prove his toughest test.
The Iran war has made this division more acute. Trump’s coalition historically included interventionists (from the George W. Bush era), advocates for restrained Middle East strategies, and hard-line isolationists. But the war forced these factions into direct confrontation: Will Republicans continue military campaigns in the region or reserve force for threats to the United States? The answer varies widely.
Vance leans toward restraint but is more willing than many senior Republicans to question U.S. commitments to Israel. These positions may resonate with much of the base while alarming interventionists, pro-Israel conservatives, and establishment donors.
Can Vance maintain relationships with controversial figures like Tucker Carlson, reconsider American commitments in the Middle East, and still hold together the Republican coalition? A competitive 2028 primary would force these questions into the open. Much of the base may share Vance’s instincts, but the right is far from unanimous.
Marco Rubio remains the likeliest challenger to Vance. He has stated he would not oppose Vance if the vice president ran, but supporters continue promoting him as a candidate. Rubio’s greater appeal to establishment Republicans and his more interventionist foreign policy could turn the primary into a direct contest over the party’s future.
One factor may be decisive: Trump’s endorsement. After the Iran war, Vance is less likely to coast through an open primary—especially if Rubio changes his mind. But Republicans might never have an open primary; Trump still commands the party he reshaped and relishes being the kingmaker.
An unequivocal Trump endorsement of Vance could end the contest before it begins. Other candidates would struggle against a Trump-Vance succession. If Trump chooses Vance, he may become the 2028 nominee by anointing rather than competition.
Trump has spoken about the race to succeed him multiple times. Once he speaks definitively, the question shifts from whether Vance can win the primary to whether the party is willing to hold one.
If Trump names Vance, he will likely become the future of the Republican Party. Trump’s decision will determine whether the party gets a primary or an anointing.
