A University of New Hampshire poll indicates Vice President JD Vance holds a commanding 51% lead among likely Republican primary voters for the 2028 presidential nomination. Vance's 42-point advantage over potential rivals like Nikki Haley and Tulsi Gabbard suggests early consolidation of the GOP base. Analysts note New Hampshire's historical role as a predictor of the Republican nominee, though Vance remains focused on current midterm elections.
