Harvard CAPS / Harris Poll · Sep 30, 2026, 19:00 UTC

Harvard CAPS/HarrisX: Vance leads 2028 GOP field 39%, but Trump Jr. surges to 24% over Rubio

In the Harvard CAPS/HarrisX September poll (fielded Sept. 26–28 among 2,200 registered voters; MoE ±2.1), Republican respondents favor J.D. Vance for the 2028 presidential nomination at 39% (−5 from August), Donald Trump Jr. at 24% (+6), and Marco Rubio at 17% (−4), with Robert F. Kennedy Jr. at 9%. The same survey shows Trump Jr. overtaking Rubio for clear second place.

Trump Jr.’s six-point jump into second over Rubio is a material reshuffle versus late-September national GOP polling that still had Rubio as the main alternative — a clear primary-race signal for the Republican nomination board.

03 / Topic

Topic Brief

The 2028 US Republican presidential nomination is the topic of who will be selected to represent the Republican Party in the next US presidential election. The supplied reviewed aggregate Market contains 42 selections, making the Event a structured view of the named individuals associated with that nomination question. The supplied record does not identify an official decision schedule, voting sequence, convention process, or other confirmed path for selecting the nominee. It establishes the topic and provides a reviewed aggregate Market with named selections, but it does not provide event-occurrence dates or official resolution sources for the broader Event. For a prediction-market reader, the durable question is how the field of named selections relates to the eventual Republican nominee. The Event page provides the topic context, while the aggregate Market presents the candidate-selection landscape without treating any individual Contract rule as a complete account of the real-world process. Markets on this topic may organize the nomination question around the aggregate field and its listed selections. Exact settlement conditions, deadlines, and other resolution mechanics belong on the relevant Market pages rather than in this evergreen topic brief.
