The 2028 Democratic presidential field remains wide open two years before primaries, with no candidates formally declared and early national polls split among Kamala Harris, Gavin Newsom, Pete Buttigieg, and Alexandria Ocasio-Cortez. This produces closely matched probabilities across the 55-64, 45-54, and under-45 brackets as traders weigh name recognition and donor networks favoring mid-career governors and former vice presidents against rising demand for generational turnover after recent older nominees. Recent state-level surveys show younger figures gaining in early states like New Hampshire, while prediction markets price AOC and Jon Ossoff higher than most polls, reflecting uncertainty over how primary voters will balance experience against calls for new leadership. Upcoming midterms and any formal announcements could shift these dynamics before the race consolidates.
