Another 2028 primary poll hints at vice presidential showdown
What the poll shows
A HarvardCAPS/HarrisX survey released Sept. 30 puts Kamala Harris at 38% among Democratic primary voters, ahead of Gavin Newsom at 17% and Alexandria Ocasio-Cortez at 12%. On the Republican side, JD Vance leads with 39%, followed by Donald Trump Jr. at 24%. The poll surveyed 2,200 registered voters from Sept. 26 to Sept. 28, suggesting the first contours of the race are already forming.
Why it matters
The numbers matter because they show early presidential positioning is already influencing the post-2024 political landscape. Harris remains the most recognizable Democrat in the field, while Vance appears to be the clearest heir to the Republican coalition if Trump leaves the scene after 2028.
What comes next
The early polling will likely fuel more maneuvering from governors, senators and party figures who are testing national appeal before 2026 and 2028 decisions harden. Candidates such as Newsom and Ocasio-Cortez may gain or lose momentum depending on whether they can expand beyond their core bases.
