FOr the most part pretty positive, I didn't watch all of it (I tuned in late). I was particularly interested in the callers, who seemed to suggest that they need a star as a candidate, and as yet, we don't have one. I know these comments are not very informative, but its the best I have. The guest (whose name I don't know) said something about Thompson's height (I gather he is quite tall, he said he is 6'6") and "looks" Presidential.
He's got a calm, deep voice, and he can seem relaxed as he puts an expression of , "I've got your number," on his face.
Those are assets when dealing with the Democrats, who like to provoke their opponents.
