The difference in Bam Bam's tone and energy level yesterday...as compared to the night before in the debate...was revealing. He is only "himself" when he is in an echo chamber. When he steps in the ring, when he is really challenged, when he can't depend on his teleprompter, he is about as tough as a jellyfish. Of course, one has to factor in the altitude effect. Apparently, the echo chamber is inversely related to the altitude.
