Kamala Harris: where things stand
The 2024 Democratic nominee retains a national base. She passed on the 2026 California governor race, keeping a 2028 run open, and says she is thinking about it.
Standing: Has led most national 2028 Democratic primary polls since spring 2026, though two summer polls (Emerson, July 19-20; Quantus Insights, August 26-28) put Pete Buttigieg first; only mid-single digits in betting markets.
Marco Rubio: where things stand
Former 2016 candidate now serving as Secretary of State, long seen as the main alternative to Vance. On September 9, 2026 he said he has "no plans at this time" to run in 2028 and is focused on his job; Wikipedia now lists him among Republicans who declined to run. He did not rule out a future campaign outright.
Standing: Placed second to JD Vance in most 2028 Republican primary polls through September 2026 (16 percent in Big Data Poll, September 13-15) and is second in the Polymarket Republican nomination market, though he now says he has no plans to run.
