Donald Trump Jr. Surges in New 2028 Republican Primary Poll
Vice President J.D. Vance currently leads the Republican field for the 2028 presidential nomination with 45 percent support, according to a recent survey from the Harvard Center for American Studies (CAPS). Despite this lead, Trump Jr. has emerged as a significant contender, polling at 21 percent and tying with Secretary of State Marco Rubio, as the political landscape shifts following the removal of Florida Governor Ron DeSantis from recent polling metrics.
Shifting Dynamics in the Republican Field
While Vance has maintained the top position in nearly all of the 50 major polls tracked by The New York Times since the start of the current administration, the latest CAPS data indicates a three-percentage-point decline for the Vice President. This softening, combined with the rise of Donald Trump Jr., suggests a tightening race for party leadership.

Trump Jr.’s entry into the top tier of polling represents a notable trend. Previously excluded from many candidate lists, his inclusion in recent surveys has consistently resulted in top-three placements. Data from Financial Times monthly polls among independent voters further supports this momentum, showing Trump Jr. securing 15 and 10 percent support in his two most recent appearances.
Did You Know? The removal of Florida Governor Ron DeSantis from polling lists in May has been identified as a factor that likely redistributed voter support toward the remaining frontrunners, intensifying the competition between Vance, Trump Jr., and Rubio.
The Competition Between Trump Jr. and Rubio
Secretary of State Marco Rubio, long considered a primary alternative to Vance, now faces direct pressure from Trump Jr. The CAPS polling shows both candidates tied at 21 percent, with only decimals separating their support levels. Historically, Rubio has been the only candidate to successfully surpass Vance in individual polls, but his recent performance has opened the door for this new competitive dynamic.
Expert Insight: Samantha Carter observes that the narrowing gap between Rubio and Trump Jr. reflects a broader volatility within the Republican base. As the party evaluates its future after the Trump era, the struggle between established figures like Rubio and the “America First” movement represented by Trump Jr. will likely dictate the primary’s trajectory.
Future Political Prospects
Donald Trump Jr. has increasingly signaled an openness to a future presidential run. During a recent meeting in Doha, Qatar, he acknowledged the possibility of seeking the nomination, telling attendees that “the call is there,” as reported by CBS News. He has consistently championed his father’s political legacy, describing the current Republican Party as the “Maga-party” and emphasizing the presence of a new generation of “America First” candidates.

Analysts suggest that if Trump Jr. maintains this trajectory, he could force a re-evaluation of the party’s ideological direction. Future developments in the race may depend on whether he chooses to formalize his candidacy or if other potential challengers, such as Tucker Carlson—who currently holds 5 percent in the CAPS poll—can capture a larger share of the electorate.
