Romney’s ‘personal character” includes six draft deferments during the VN war - for college, foreign missionary work, and marriage. So others took the place of Mr. Romney in the Army or Marines bc he had such “personal character”.
But he is a character, who is despised by many. Thus he has no room to talk about the character of others. The Lord may even admonish him for bearing false witness, not that Trump is a saint, but that it’s not his place to judge, lest he be judged.
