I"m not so sure
There isn't another Trump on the horizon unless its Vivek
in 2028 if people have to choose between a woman Veep that Trump picked and DeSantis who kills its as governor for 2 more years and then go on a rehabilitation tour, I bet people will change their tune about him in 2028.
Now if there is a person that Trump can hand the torch off to that people like then yea, DeSantis is going to have trouble.
What he needs to do at this point is kiss the ring and not be a butt hurt asshat like Chris Christie
