The Heir Apparent: JD Vance and the 2028 Republican Landscape

Vice President JD Vance occupies the position that historically serves as a launching pad to the presidency. Yet prediction markets give him only a 23% chance of winning the 2028 election—suggesting the path from understudy to president remains treacherous.

The Vance Position

At 41, Vance is the youngest vice president in decades. He's positioned himself as the intellectual architect of Trumpism, articulating a coherent populist-nationalist philosophy that goes beyond Trump's instinctual politics. His bestselling memoir and Ivy League credentials give him crossover appeal that few Trump allies possess.

Markets price his 2028 presidential win at 23% on Manifold, with his nomination probability significantly higher at around 35% on Polymarket. The gap tells a story: forecasters think he's likely to win the Republican nomination but less certain he'd win the general election.

The Competition

Several factors keep Vance's odds relatively modest:

Ron DeSantis remains a factor despite his 2024 disappointment. Florida's governor has rebuilt his standing through effective state governance and could mount another campaign.

Trump's shadow will hang over any successor. Can Vance mobilize Trump's coalition without Trump himself? The MAGA base is famously personal in its loyalties.

New entrants could emerge. Tucker Carlson's media platform has positioned him for potential political runs. Tech figures like Vivek Ramaswamy could return. The Republican field is unpredictable.

The Historical Pattern

Vice presidents seeking the presidency face a mixed record. George H.W. Bush won in 1988 as Reagan's VP. Al Gore and Richard Nixon (in 1960) lost their first attempts. The position provides advantages—name recognition, fundraising networks, apparent experience—but also burdens. VPs inherit their president's enemies while sometimes being overshadowed by their boss's achievements.

What Markets Suggest

The 23% probability for Vance to win it all, combined with ~35% nomination odds, implies markets see the general election as his bigger challenge. This could reflect concerns about:

• His relative inexperience in national campaigns
• Potential Democratic enthusiasm against Trumpism's continuation
• Economic conditions in 2028 (unpredictable from today)
• His specific policy positions on trade and immigration

Trump's Health Factor

One underappreciated variable: Trump would be 82 at the end of his term. Markets price a 20% chance that Trump doesn't finish his second term due to death or serious illness. If that occurs, Vance becomes president—fundamentally changing the 2028 calculus.

An incumbent President Vance running in 2028 would likely see much higher odds than Vice President Vance.

Conclusion

JD Vance is the early frontrunner for 2028, but "frontrunner" in a wide-open field means relatively modest probabilities. At 23%, he's the most likely individual to win—but the field collectively is far more likely to produce someone else. Three years is an eternity in politics, and the markets know it.
