Florida Governor Ron DeSantis has risen in prediction market projections to succeed Donald Trump as the Republican presidential nominee in 2028. The shift follows the November 3, 2026, midterm elections, in which the Democratic Party gained dozens of seats to take control of both the House of Representatives and the Senate. According to data from Polymarket, DeSantis’s standing rose 9 percent since Thursday, November 5, 2026, placing his odds at 13 percent.
The Republican Party is currently assessing the midterm results, with some members attributing the losses to President Trump’s policies. Specifically, critics within the party cited the war in Iran and the response to the cost of living crisis as factors for the electoral outcome. Vice President JD Vance, who is currently the projected front-runner with a 34 percent chance on Polymarket as of Thursday morning, stated on social media on Wednesday, November 4, 2026, that "the reason we lost is the war."
Vice President Vance has reportedly sought to distance himself from the administration’s decision to launch Operation Epic Fury airstrikes against Iran. According to reports from Axios, Vance had privately warned the president that the conflict was unpopular and could impact the midterm elections. Other figures identified as potential 2028 contenders include Secretary of State Marco Rubio, who currently holds 17 percent odds on Polymarket, and media personality Tucker Carlson, who holds 3 percent.
In a television appearance on Wednesday, November 4, 2026, Governor DeSantis described the midterm results as a "rebuke" of the president and the Republican-led Congress. He characterized the previous legislative session as having "a lack of productivity." While DeSantis is gaining momentum in current projections, he previously sought the Republican nomination two years ago without success. Secretary of State Rubio, whose home state of Florida remained Republican in the midterms, has stated he has no intention of running if Vice President Vance enters the race.
For the American electorate, these developments signal a possible change in the direction of U.S. foreign involvement. If the party moves toward candidates like Vance or Carlson, who have voiced opposition to the war in Iran, voters may see shifts in military spending or diplomatic relations with Israel. The scale of the recent midterm shift involves dozens of seats in Congress, transferring legislative power to Democrats who will now set the agenda for the next two years.
The next steps for these potential candidates will involve navigating the final two years of the Trump administration. Observers will monitor whether Secretary of State Marco Rubio or Defense Secretary Pete Hegseth, who has been a primary spokesperson for the Iran conflict, maintain their current standing or face further criticism for administration policies. The official primary season for the 2028 election will not begin for several years, but the current prediction market trends reflect the impact of the 2026 midterm results on the party's future leadership.
