“Now the question is will DeSantis challenge him for the nomination?”
Why antagonize such a question? There is no riff between DeSantis and Trump, no matter how much you try to insinuate there is.
It's a honest question. Ignoring President's record, much of what we can be proud about, we have to look at his age. He will turn 78 in 2024. He has been aging well but father time will win at the end. We are all witnessing what is happening to Biden due to his aging.
