How about the Convict-in-Chief? Or if that makes it sound too much like he’s going to get back to the Oval Office, either Convicted Felon Donald Trump or (as a jazz reference) Felonious Trump would work.
Dotard J. Trump?
Or just give Trump one of the biggest insults you can: don’t use his name at all. “Do you really think a bigoted, insecure old man like my opponent has the energy needed to run this country?”
