Senator Marco Rubio has pledged his support for Vice President JD Vance should Vance run for president in 2028, marking a significant early endorsement that could shape the Republican primary landscape. In a mid-December 2025 interview with Vanity Fair, Rubio stated, “He’s going to be our nominee, and I’ll be one of the first people to support him.”

Rubio’s declaration is considered a rare act of political deference, signaling unity within the party and solidifying Vance’s status as an early frontrunner among GOP circles. As Secretary of State under President Donald Trump, Rubio’s backing carries substantial weight, aligning with Trump’s October 2025 suggestion of a potential Vance-Rubio ticket.

The endorsement also echoes recent organizational support, including Turning Point USA’s public backing of Vance, reinforcing the former venture capitalist’s early momentum. Political analysts note that Rubio’s commitment not only positions Vance advantageously in the 2028 race but also signals a continuity of Trump-era policies and alliances within the Republican Party.

While the 2028 election remains several years away, Rubio’s early and explicit support may influence donor confidence, grassroots organizing, and party endorsements, shaping the initial contours of the GOP primary well before official campaigns begin.
