Caren, am I completely naive? Donald can't be running again? Initially he ran and won because voters gave him the benefit of the doubt -- he would come up to speed once in office. He didn't do that and Biden (the old fool) in the next presidential election won.
The Republicans would be entrenching themselves in defeat to have Donald as their nominee. They could be placing their bets against an old dithering Biden to hang around for a second term.
Democrats have plenty of talent ready to be a better alternatives. They should make use of it.
Best to you.
