The 2028 Democratic presidential field remains wide open more than two years before the convention, leaving the vice presidential nominee market fragmented with no candidate above 18% in trader consensus. Multiple governors, senators, and House members who could seek the top spot have not yet declared intentions or built dominant coalitions, preventing any single VP prospect from pulling ahead. Recent state legislative and gubernatorial results plus ongoing party positioning have yet to produce decisive signals on ticket-building preferences. Primary debates, early endorsements, and polling trends among likely presidential contenders could create separation once a frontrunner emerges and begins narrowing the shortlist.
