I saw a video some months back where he was replying to the question, he said he planned to fulfill his term to the people of his state. I knew then that he was slime because it was obvious he was making other plans. I’m sure it’s around someplace.
It was obvious to you, and every Floridian that DeSantis was being considered as a presidential candidate - and that he was considering a run.
It was openly talked in the debate with Crist and he (DeSantis) did not commit to serving an additional four terms as governor.
Every Florida voter knew it was a possibility. Those that didn't like those terms - or just didn't like DeSantis - voted against him.
That said, most Floridians accepted the terms and reelected him overwhelmingly.
President Trump himself accepted those terms and jumped aboard the DeSantis reelection bandwagon.
You have not claimed you “had no idea.” If fact you have said just the opposite.
There are real reasons to prefer Trump over DeSantis. You ought to find one of those real reasons and talk it up.
