I think they do too but Trump as the nominee is going to turn them off from voting for him. They don't like him and even less people don't like to admit mistakes. Voting for Trump after voting for Biden is admitting a mistake.. And you are correct it has nothing to do with policy.
They won't hold their nose and pull the lever for Trump.
I respectfully disagree. And the left will eat Desantis alive for his positions while he won't energize the rust belt because everyone knows his foreign/economic policy is cut from the same cloth as people like Romney/McCain.
Complete unelectable on a national level.
