WTH are you talking about?
It is a rational position. Trump is not someone who will blindly and faithfully follow tradition. He will lash out in rage if (God forbid) he loses. He will resign the morning after, make Pence the President and ask him to pardon him so he can leave town. I don't see Trump silently suffering for 2 whole months the indignity and disdain that will come his way if he loses.
