As of October 2026, no major-party candidates have formally declared 2028 presidential campaigns, with only minor and fringe figures having filed Federal Election Commission paperwork. Serious contenders are expected to emerge after the November 2026 midterms, consistent with historical patterns of announcements clustering in 2027. Early positioning includes public comments and campaign appearances by potential Democratic figures such as Kamala Harris, Gavin Newsom, Pete Buttigieg, and Alexandria Ocasio-Cortez, alongside Republican names like Vice President JD Vance and Senator Ted Cruz. Recent national polls show Harris and Vance leading their respective hypothetical primary fields, while structural factors including term limits for President Trump and post-midterm momentum will shape declaration timelines.
