**Vance maintains a consistent lead as the early frontrunner for the 2028 Republican presidential nomination, with national primary polling averages showing him ahead of Rubio by roughly 15 points and prediction markets pricing Vance near 50 percent while Rubio sits around 15-20 percent.** Rubio has publicly stated he has no current plans to seek the nomination and would support Vance if the vice president runs, reducing immediate competitive pressure. Both figures hold senior roles in the Trump administration, and the race remains more than two years from the first primaries, with no candidates formally declared and midterms still ahead. Trader consensus at 97.7 percent for "No" reflects this stable positioning and Rubio's deferral. Late developments such as a major scandal, health event, sharp polling reversal, or explicit Trump endorsement shift could theoretically alter the dynamic before October 31, though none appear imminent.
