I have to give her props for doing this well. I expected DeSantis to be the last one standing among the also-rans.
She has the advantage of having all the Democrat and RINO fake supporters - they don’t actually want her to be POTUS, they are just trying to weaken Trump. She has no reason to drop out since she’s not in it to win anyway.
DeSantis supporters are actual Republicans who want a Republican to win. Once they see it’s not going to be DeSantis, they mostly switch over to Trump, however reluctantly.
That’s why DeSantis dropped out before Haley - he would rather a Republican win even if it’s not him.
Good for him - better late than never.
