Potential 2028 presidential contenders from both parties have begun early positioning through polling visibility, primary-state travel, and public statements, though no major candidates have formally declared. Vice President JD Vance leads Republican primary polling averages, while former Vice President Kamala Harris tops Democratic surveys, with figures such as Rep. Alexandria Ocasio-Cortez, Gov. Gavin Newsom, and former Transportation Secretary Pete Buttigieg also frequently mentioned. Recent developments include Newsom stating in September 2026 he would not run if Harris enters, Marco Rubio indicating no plans to run, and Sen. Ted Cruz reiterating long-standing interest in the presidency. The November 2026 midterms and subsequent months represent key windows when exploratory activity and formal announcements could accelerate ahead of the 2028 primaries, consistent with historical patterns of candidates declaring roughly one year before voting begins.
