Vice President J.D. Vance and Robert F. Kennedy Jr. remain locked in a near-even contest for the 2028 Republican presidential nomination, with traders pricing both near 50 percent amid limited separation from the broader field. Vance's position as the sitting vice president, his keynote address at the recent Republican midterm convention, and consistent leads in early national polling averages have anchored his support as the perceived MAGA successor. Kennedy's strong showing reflects his cabinet role and appeal on specific policy issues. Emerging intra-party tensions, including public exchanges involving senators like Ted Cruz, and focus on the 2026 midterms introduce uncertainty, as outcomes there or shifts in primary dynamics could widen the gap before formal campaigning intensifies.
