Trump shows up. He is ready for action standing behind the podium looking presidential.
Now Hillary has three choices. The first she has pneumonia and can't make it. The last nail in her coffin. The press will try to substitute Obama for Hillary. Trump won't allow it.
Second, she shows up and has a health issue during the debate. See the last nail above.
Third she makes it through the debate and let's everyone see how bad she is. Trump wins again.
Bring on the debate.
Fourth, Trump stands on the stage alone and takes questions from the moderators?
