On Tuesday night, the mother of Trayvon Martin praised Hillary Clinton at the Democratic National Convention in Philadelphia for having the courage to lead the fight for common-sense gun legislation. Numerous other speakers also raised the gun control issue at the DNC, too. But Wednesday night was clearly gun night. From Senator Chris Murphy (D-Conn.) to former Philadelphia Police Commissioner Charles Ramsey to former Representative Gabby Giffords and her husband, NASA Astronaut Mark Kelly to others, a string of speakers pushed for more gun control.
