Ron DeSantis did run for president in the 2024 election cycle, announcing his candidacy for the Republican nomination on May 24, 2023 and later suspending his campaign on January 21, 2024, after a poor primary showing. (en.wikipedia.org) However, he did not become the Republican nominee and therefore could not, and did not, win the 2024 general election—let alone by a “landslide.” The prediction bundled two claims (that he would run and that he would win in a landslide); since the second, outcome-defining part is clearly false, the overall prediction is wrong.
