With the 2028 Republican presidential nomination still years away, traders have distributed support across a broad field of potential vice presidential nominees, leaving Marco Rubio in the lead at 31.5% on the strength of his Senate leadership position and foreign policy background. Kristi Noem at 14.5% and John Thune at 10.5% follow as prominent figures with executive and legislative experience that could appeal in a general-election context. Lower-priced options such as Marjorie Taylor Greene, J.D. Vance, and others reflect fragmented early interest, with no candidate yet consolidating backing. Differentiators include national visibility, alignment with key party priorities on issues like immigration and trade, and future performance in Senate or gubernatorial roles that could shape ticket dynamics ahead of the convention.
