At a town hall held by CNN in Sunrise, Florida, on Wednesday night, thousands of angry students, teachers and parents booed Republican Sen. Marco Rubio when he indicated that he would not support an assault-weapons ban and applauded Dem. Rep. Bill Nelson when he pushed Rubio to work on a bill that they both could support. They also booed a spokeswoman from the NRA when she said the answer was not to ban weapons but to ensure they stay out of the hands of the mentally ill.
