There were maybe three who said nasty or stupid things, however in a flat tone of voice. One assumes that the CSPAN gatekeepers gave them strict instructions not to go full-postal, because the producers have the ten-second delay and can take them off the air.
So I guess I'd call them "restrained deranged."
Still, the calls ran about 70-75% positive.
Great news!!
Thanks, much for the update!!
