I could buy these numbers in the Senate race, but not in the Gubernatorial race.
Rubio will outrun DeSantis quite comfortably and likely win by double digits.. not sure why you would buy these numbers for Senate.
Rubio is less in touch with the Republican base than DeSantis is. DeSantis, in my opinion, will comfortably outrun Rubio.
The Republican base isn't the entirety of Florida and you need more than that to "landslide" in the state..
Rubio in 2016 carried Hillsborough, only lost Miami Dade by 11 while Trump got crushed .. I expect him to do so again and improve on that performance.
