Jon Ossoff leads the 2028 Democratic nomination market at 26.7% following his strong November 2026 reelection in Georgia, which contributed to Democratic gains in both chambers of Congress and highlighted his appeal in a swing state. Alexandria Ocasio-Cortez sits second at 16.3%, buoyed by progressive midterm successes and positioning as a generational alternative. Polling averages show Kamala Harris ahead in the low-to-mid 20s percent range, with Gavin Newsom, Pete Buttigieg, and others trailing, though prediction markets assign lower probabilities to those figures amid uncertainty over 2024 outcomes and candidate intentions. Newsom has indicated he would defer if Harris runs. Key differentiators include Ossoff’s electability narrative versus AOC’s base mobilization, governors’ executive records, and senators’ fundraising or national profiles. Consolidation could occur through early primary performance, endorsements, fundraising totals, or shifts in party direction between moderate and progressive priorities ahead of formal declarations.
