There's a chance for Ron DeSantis to be a strong contender due to what he has done about the racist and another state affairs but him supporting Trump when he was President could also make some people ought to support him (Ron) doubt him. Besides, he's a politician and one of the good things he has once done is to be used to make a campaign for his coming election.
As I said before, it too early.
Ron DeSantis will be 46 years old by the time of the next POTUS elections. He is young, but at the same time he has tons of experience. I would prefer someone like him to be the Republican nominee than either Donald Trump (who will be 78 years old in 2024) or Ivanka Trump (who doesn't have any real political experience). If the GOP nominates another 75 plus candidate, then it is going to get really tough for them to win the voters they lost between 2016 and 2020. Also, states like Texas will be in play by 2024. They need someone who can attract the Latino votes as well.
