The 2028 presidential nomination contests remain fluid after the 2026 midterms, with no major candidates formally declared. Republican frontrunner JD Vance, the sitting vice president, would be in his mid-40s at the January 2029 inauguration. On the Democratic side, early polling leaders such as Kamala Harris would be in her mid-60s, while Alexandria Ocasio-Cortez or Pete Buttigieg would be in their late 30s to mid-40s. Trader focus centers on which party’s nominee emerges, given wide age gaps among the leading names and the absence of declared campaigns or decisive polling shifts this early in the cycle.
