He’s insulating himself in case the debate doesn’t go well for him. He’s one seriously shrewd and energetic dude.
I have a feeling he should be most concerned about Hewitt. He is a GOPe for Jeb and Kasich. Gotcha questions about the Foreign Minister of Dirkadirkastan that no one would know unless they were fed the info ahead of time. The others are Dems and are just gonna pull out the ordinary Dem clap-trap of irrelevant issues because they support Hillary or Biden.
