> Unless Trump is just toying with us all, it is hard for me to imagine him being able to continue his 'campaign'.

Perry is close to zero in the polls and has nothing to lose by slamming him. The same goes for Lindsay Graham.

Trump has already laughed Perry off. His support hasn't been affected, any more than it was when he attacked John McCain as not heroic enough. He will stay in the race until he gets bored. He's already threatened to run as a third party candidate if other Republicans aren't nicer to him.

Trump knows that they know that if he does run independently, Hillary Clinton will almost certainly win.

Stay tuned.
