The 2028 Democratic vice presidential field remains tightly clustered because no single contender has consolidated support this early in the cycle. Leading options such as Chris Murphy, Alexandria Ocasio-Cortez, and Raphael Warnock sit in the low-to-mid 30s as traders weigh a wide bench of senators, governors, and House members still testing alignments after the prior election. The 2026 midterms and subsequent party positioning will likely narrow the pool, yet current pricing shows broad uncertainty over which profiles—ideological, geographic, or demographic—will best complement the eventual presidential ticket. Late developments in primaries or coalition negotiations could quickly shift shares among the top tier.
