About Marco Rubio and 2028

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.

Recent 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.
