I think it's that everyone knows Hillary is a flawed candidate that should be beatable. She has only the Dem party line to follow and we see what that has done for us for 8 years.
She also has the email scandal. Even though the current corrupt administration will not indict her , it will be a major issue to hit her with during the election. Hillary is probably the weakest candidate the Dems have put up.
So if your Mit, and you blew your chance when you got tag teamed in the debate by obvious collusion between the administration and the moderator, you've got to be eating your heart out that a total outsider is about to become the nominee. It would drive me crazy if I came that close.
True, Romney was set up in the debate by the moderator and Obama. Romney however is 100% guilty of laying down in the 2nd and 3rd debated. That is really why he lost. It was almost as if he was told to take a fall.
