Trump isn’t going to lose face, it is a deep Red State.
You know that. I know that. But I want you to pay attention to the media when Moore wins. Public perception is face and the media will do what it does, and attack Trump over this. They will say the people are turning against him. That he has lost his base. I could write the articles myself and I'm sure they are already written just waiting for some pencil neck to hit the send button.
Yes, his backing the wrong horse will be used against him. Watch and see. Red state or not.
The media will spin it as an embarrassing set back for President Trump and high light the fact that a number of notables from his own base supported Moore.
