6/28/2026, 8:55:19 PM
Current Contest for the 2028 GOP Nomination
Republican voters are weighing Vice President JD Vance against Secretary of State Marco Rubio as the likely successors to President Donald Trump in the 2028 presidential race. Both men are serving in the Trump administration—Vance as vice president and Rubio as both secretary of state and national security adviser—while the president remains publicly non-committal about endorsing either candidate.
Background and Recent Developments
Vance, a former Ohio senator and Marine Corps veteran, was elevated to the vice presidency in 2025. He has promoted his new memoir, *Communion*, and has been a point-person in the administration’s negotiations to end the conflict with Iran, despite earlier opposition to the war. Rubio, a former 2016 GOP presidential contender, has been tasked with aggressive foreign-policy initiatives in Venezuela, Iran and Taiwan, and is widely praised by Trump for his diplomatic work.
Key Players and Potential Rivals
- JD Vance – Vice President, author, former senator from Ohio.
- Marco Rubio – Secretary of State, National Security Adviser, former Florida senator.
- Donald Trump – Incumbent president, whose endorsement could decide the nominee.
- Other names mentioned in prediction markets include Donald Trump Jr., Florida Gov. Ron DeSantis, and former Fox News host Tucker Carlson.
Polling and Prediction-Market Data
- McLaughlin & Associates poll (June 17-23, 464 likely voters): Vance 35 % vs. Rubio 15 % among Republicans.
- AtlasIntel poll (May 4-7): Rubio leads with ~45 % while Vance trails.
- Emerson College poll (late May): Vance 36 % vs. Rubio 35 %.
- Prediction-market odds (Kalshi, June 2026): Vance ~40 %, Rubio just under 30 %; Trump Jr. and DeSantis each ~5 %; Carlson ~4 %. Trading volume approaches $50 million.
Official Statements from the Candidates and the President
President Trump has declined to endorse a successor, noting only that a “perfect ticket” could pair Vance and Rubio. Vance told USA TODAY that he is focused on helping Republicans win the 2026 midterms and on performing his vice-presidential duties, warning against premature speculation about future jobs. Rubio, speaking to NBC News, called Vance “a very good friend” and said he would be “a phenomenal candidate” if Vance ran. Republican strategist Alex Conant argued that Vance’s vice-presidential status makes him the natural frontrunner, while political scientist Matthew Dallek warned that Trump’s loyalty to allies is historically unpredictable.
Criticism, Opposition, and Intra-Party Tensions
Critics note Vance’s public opposition to the Iran war and his criticism of Israel, positions that could alienate the party’s foreign-policy hawks. Rubio’s strong support for the Iran intervention and for Israel aligns him with the grassroots GOP but raises questions about his independence from Trump. Observers also point to the transactional nature of Vance’s relationship with Trump and the potential for other contenders—DeSantis, Trump Jr., Carlson—to reshape the field if Trump’s endorsement remains undecided.
Conflicting Reports and Gaps
Polls differ sharply on who leads the Republican primary, with Vance ahead in some surveys and Rubio ahead in others. Prediction-market odds favor Vance, yet they cannot capture the impact of a possible Trump endorsement. No definitive statement from the White House clarifies Trump’s preferred successor, leaving a key variable unresolved.
