JD Vance Leads 2028 GOP Primary as Marco Rubio Gains Ground

Vice President JD Vence holds a solid lead in the Republican race for the 2028 presidential nomination, commanding about 48% of GOP primary voters and a 60%‑to‑29% advantage over Secretary of State Marco Rubio in head‑to‑head polling. Rubio, however, has narrowed the gap, climbing to roughly 18% in recent polls and reaching a 16% chance of winning the general election on the Kalshi prediction market, edging Vence’s 15% chance.

Vence has not formally announced a candidacy for 2028, though speculation suggests he may seek the White House with implied support from former President Donald Trump. Rubio has publicly said he would not challenge Vence in a primary, while other potential contenders such as Florida Governor Ron DeSantis and Texas Senator Ted Cruz trail significantly.

The evolving dynamics show a tightening race within the GOP, with Vence remaining the clear frontrunner but Rubio emerging as a notable challenger ahead of the 2026 midterms.
