Greedy people have a hard time delaying gratification.It'd be better for de Santis to let Trump be the front runner & let him lose so that he can position himself as the undisputed front runner in 2028. Otherwise if he challenges Trump the votes won't be behind him since teh Republican Party is very fractured. however if there is no one in his way in 2028 de Santis will have the entire party behind him in in 4 or 5 years.
