The Democratic vice presidential slot for 2028 sits in a fragmented field where no contender exceeds single-digit implied probability, reflecting the absence of a presumptive presidential nominee and limited early consolidation. Alexandria Ocasio-Cortez leads at 10 percent on the strength of her national profile and progressive donor base, while governors such as Andy Beshear and Wes Moore sit just behind on records of winning in competitive states and demonstrated executive experience. Other names draw support from Senate tenure, fundraising reach, or demographic appeal. Key variables that could shift probabilities include 2026 midterm results, early endorsements from party leaders, primary polling trends, and any signals from potential presidential contenders about preferred running mates.
