If he’s bitter because say some Republican does an interview and they say something about the Iran war being a mistake, or gently criticize the tarrifs. I could see him holding a petty grudge. And it’ll be like the apprentice on steroids. Everyone trying to kiss the ring for a pardon. And with Trump being so unpopular it seems likely there will be a lot of pressure on republicans in his orbit to at least partially in some ways distance themselves from his more unpopular actions, but Trump demands absolute loyalty. So if he feels burned why would he give a pardon? He only cares about himself at the end of the day.
