Will he resign? I doubt it. That is not the thing to do these days. What do you do, you ask? You trot out your wife and do a press conference saying how sorry you are and then go into hiding until it all blows over.

It is a shame what these women have to endure during these times. I feel sorry for them, but I do not think they should allow themselves to be used this way.
The reason I posted this is to tell you this: If you ever were to see me do a press conference after something like this (which you won't), My wife would not be there. And I would be recovering from gunshot wounds, or stab wounds. That is if you were not attending my funeral.
