That really isn’t De Santis’ call.
If God or Trump decides Trump isn’t running, then from what I see, I’d hope that DeSantis will run.
Trump has always struck me as the sort of person who calls his own number a little too much, but in the end that is between, him, God and whomever else he seeks advice from. In the end he was clearly better than nearly all of the other options in 2016 (or 2012, or 2008, or 2004, or 2000). I wouldn’t want to argue that he was clearly inferior to any from those years.
It is also up to those who vote wisely.
Governor DeSantis has more work to do in Florida - he’ll be good to go for the Presidency in 2028.
We’ll need President Trump, beginning in 2025, to spend four years cleaning up the HUGE mess/disaster/catastrophe that Sloe Joe, The Hoe and their criminal conspirators will have made.
Then, DeSantis can come in, finish up whatever still needs to be done (probably not much!) and enjoy 8 years of peace and prosperity!
That is my vision, anyway!
